Premise

The first season begins on October 6, 1997, in the quiet industrial town of Briar Glen. A partial collapse at the long-abandoned Bellridge Research Facility triggers a wave of strange occurrences, including memory blackouts, distorted broadcasts, and unexplained behavioral shifts. Sixteen-year-old Iris Ward wakes up in the woods with no memory of how she got there, sparking a chain of events that leads her and her friends—Luca Grayson, Kendra Vale, Cam Russo, and Isla Moreno—into a deepening mystery tied to a long-dormant government experiment. As the group investigates, they uncover a forgotten transmission known as the Bellridge Signal, a corrupted frequency capable of rewriting memory, disrupting perception, and revealing buried truths the town was never meant to remember.

1	1	"Chapter One: The Static Below"	Freddie Goodwin	Freddie Goodwin	July 18, 2024
On October 6, 1997, the small industrial town of Briar Glen is rocked by a partial collapse at the defunct Bellridge Research Facility, a Cold War-era compound sealed off since the 1970s. That night, several residents report high-pitched ringing in their ears, sudden memory lapses, and distorted power signals, but local authorities dismiss the incident as a minor seismic event. The next morning, sixteen-year-old Iris Ward wakes up in the woods two miles from her house with no recollection of how she got there, her clothes damp and her watch shattered. At school, she reconnects with her childhood friend Luca Grayson, a quiet audio tech obsessive who claims to have recorded a strange frequency the night of the collapse. As Iris starts experiencing hallucinations—glimpses of people frozen in place, lights flickering in rhythm, whispers with no source—she confides in Luca, who says the signal pattern isn’t random, but structured like a language. Meanwhile, school janitor Alan Ridgeway is seen entering a locked wing of the school late at night, carrying an old reel-to-reel recorder marked "Bellridge: 5.3." As Iris, Luca, and their classmates Cam and Isla begin to piece together fragments of a hidden signal spreading through the town’s infrastructure, they discover the original Bellridge project was never shut down—it simply changed frequency.
2	2	"Chapter Two: Repeater"	Freddie Goodwin	Freddie Goodwin	July 18, 2024
As Iris begins to track her blackouts, she realizes they coincide with specific electrical surges across town—each one echoing the distorted signal Luca recorded. The group stakes out an old radio tower on the outskirts of Briar Glen, where Luca believes the transmission is being amplified. There, they discover a rusted signal repeater wired into power lines still active despite being disconnected from the grid since 1981. Cam uncovers archived town maintenance logs suggesting covert work orders were issued to keep the tower functional under a false utility company name. Meanwhile, Isla explores the locked wing of the school after noticing janitor Alan Ridgeway vanishing behind it nightly. Inside, she finds sealed crates labeled with matching Bellridge tags and faded blueprints of the facility's sublevels. At home, Iris's symptoms escalate—she experiences a full blackout and wakes up standing at the center of her family's living room, surrounded by rearranged furniture, broken clocks, and a low humming she can’t locate. The episode ends as Luca plays the repeater’s raw transmission through his equipment and, layered beneath the static, they all hear it clearly for the first time: a voice repeating Iris’s full name.
3	3	"Chapter Three: The Voice in the Tape"	Freddie Goodwin	Freddie Goodwin	July 18, 2024
Luca isolates the voice from the transmission and slows it down, revealing that it’s not only repeating Iris’s name—it’s also reciting coordinates tied to locations across Briar Glen, including an abandoned storm drain near the edge of the woods. The group investigates the site and discovers signs of recent activity: boot prints, melted electronics, and fragments of magnetic tape embedded in the soil. Iris begins having vivid sleepwalking episodes, waking up in different parts of town with short bursts of audio burned into her memory—distorted voices, strange countdowns, and mechanical pulses. Meanwhile, Isla confronts Ridgeway, who cryptically warns her to stop digging into Bellridge, saying the signal was “never meant to wake anything.” At school, Cam’s phone picks up a scrambled voicemail from a number that no longer exists, containing audio identical to what Luca extracted from the repeater. Tension builds as Iris secretly follows the latest coordinates and discovers a half-collapsed tunnel beneath the town’s train station, its walls etched with arcane markings and decayed speakers wired into the rock. The episode ends as Iris hears the voice again—this time clearly saying “return to phase”—before a loud frequency surge knocks out every light in the tunnel and leaves her alone in total darkness.
4	4	"Chapter Four: Phase Return"	Freddie Goodwin	Freddie Goodwin	July 18, 2024
In the aftermath of the blackout, Iris stumbles out of the tunnel disoriented and shaken, with a high-frequency tone ringing in her ears that won’t fade. Luca analyzes the recording from her phone and discovers the frequency surge forms a waveform signature nearly identical to brain scan readings, suggesting the signal is interacting neurologically rather than electronically. Cam hacks into a restricted municipal database and uncovers a series of classified files marked “PHASE RETURN,” dating back to the early 1970s, referencing experiments in cognitive signal entrainment conducted at Bellridge. Meanwhile, Isla follows Ridgeway to a derelict warehouse on the town’s outskirts, where she witnesses a strange ritual involving looping broadcast equipment, synchronized metronomes, and people standing motionless in silence. As Iris’s mental state begins to fray, she admits to the group that she no longer knows whether certain memories—like childhood conversations or specific dreams—are real or planted by the signal. While attempting to retrace her route through the tunnel, she and Luca discover an old Bellridge access hatch hidden under a concrete slab in the school’s boiler room. Inside is a long-forgotten monitoring station with decayed files, redacted schematics, and reels labeled “Subject 8A: Signal Retention – Adolescent Patterns.” As they listen to one of the tapes, the room begins to hum—matching the rhythm of Iris’s heartbeat.
5	5	"Chapter Five: Subject 8A"	Freddie Goodwin	Freddie Goodwin	July 18, 2024
The tape reveals distorted interview logs with a teenage girl subjected to prolonged exposure to the Bellridge signal—her voice eerily similar to Iris’s. Luca theorizes that Iris may be somehow neurologically linked to the original experiments, possibly as a genetic match or residual imprint. The group becomes divided on how to proceed; Cam wants to go to the authorities, while Kendra insists that doing so would only bury the truth deeper. Meanwhile, Isla secretly returns to the warehouse and discovers dozens of vintage CRT televisions arranged in a circle, all displaying static until she steps inside—where the screens shift to show grainy footage of Iris sleepwalking. Iris begins losing blocks of time altogether, waking up with ink markings on her arms resembling diagrams found in the Bellridge schematics. At school, Ridgeway vanishes, and a substitute janitor arrives who seems to know far more than he lets on. Luca tracks the “Subject 8A” project to a specific sublevel of the facility, long since sealed in a cave-in, but Iris begins having dreams—memories—of being there. After following a new signal burst to an old water tower outside town, the group finds an abandoned technician’s station covered in old photographs, some of which clearly show Iris’s face—decades before she was born. The episode ends with the realization that Bellridge didn’t just broadcast—it recorded. And something is still listening.
6	6	"Chapter Six: Playback"	Freddie Goodwin	Freddie Goodwin	July 18, 2024
As the group reels from the discovery of Iris’s image in the decades-old photographs, Luca uncovers that Bellridge’s signal may not only record memories but also replicate and overwrite them, raising the possibility that Iris herself could be a construct of the experiment—part organic, part archival. Iris begins experiencing “playbacks,” moments where reality glitches and replays recent events with slight alterations, such as conversations repeating with different outcomes or people appearing in places they hadn’t been. Kendra searches the town archives and finds a sealed court record from 1974 referencing the disappearance of multiple children linked to Bellridge, all of whom shared behavioral symptoms matching Iris’s current condition. Meanwhile, Isla grows increasingly paranoid after discovering that her own handwriting matches annotations in the Bellridge blueprints, despite never seeing them before. Cam, struggling to stay grounded, becomes convinced they’re all being observed and installs an analog camera system around the school, only to capture footage of Iris standing silently in hallways she never remembers entering. The substitute janitor leaves behind a box of cassette tapes labeled “Echo Logs,” which play only white noise—until Iris is present, at which point they begin to speak in her voice, recounting thoughts she never remembers having. As playback events increase across Briar Glen—glitches in power grids, repeated sirens, overlapping radio signals—the group realizes the signal isn’t isolated to Iris. It’s spreading.
7	7	"Chapter Seven: Echo Chain"	Freddie Goodwin	Freddie Goodwin	July 18, 2024
The spread of the playback phenomena intensifies across Briar Glen—streetlights flicker in rhythmic loops, school announcements repeat phrases that were never spoken aloud, and several students begin reporting lost time and fractured memories. Iris’s condition deteriorates as her own identity starts to blur; she forgets details about her family, finds new scars she doesn’t recall getting, and begins to refer to herself in the third person during blackouts. Luca tracks the origin of the “Echo Logs” to a decommissioned utility hub that once powered the Bellridge facility, discovering it still draws energy during specific lunar cycles. There, he uncovers a vast audio map stitched together from thousands of overlapping signal fragments—recordings of voices, events, and moments layered into an evolving pattern. Meanwhile, Kendra and Cam locate a hidden room beneath the school’s auditorium containing projectors and file cabinets filled with documents about “Echo Chain Events”—a Bellridge contingency plan designed to allow memory loops to propagate across a population for long-term observational studies. Isla becomes the next to experience playback symptoms, repeating an entire day’s actions without realizing it until shown evidence by the group. As Iris begins responding to voices in the signal that no one else can hear, the group confronts the possibility that the line between original thought and broadcast memory has collapsed. The episode ends with Iris standing at the center of the school gym during a late-night storm, her voice broadcasting through every speaker in town—repeating a phrase she has no memory of ever saying: “Phase return complete.”
8	8	"Chapter Eight: The Bellridge Event"	Freddie Goodwin	Freddie Goodwin	July 18, 2024
As Briar Glen descends into chaos, with overlapping broadcasts, memory fractures, and reality distortions affecting more of the population, the town effectively shuts down. Emergency services collapse under system-wide interference, and reports surface of people reliving entire days or vanishing mid-sentence. Luca decodes the final layer of the signal and discovers that the entire network is converging on a scheduled broadcast first initiated by Bellridge decades ago—a one-time event designed to trigger full-phase synchronization across all affected minds. The coordinates point to the original Bellridge sublevel, long thought inaccessible, now reactivated by the signal’s reawakening. The group prepares to descend into the ruins of the facility, piecing together that Iris may be the final node—her brain mapped as a central carrier, unknowingly used to store and transmit the system’s core architecture. As they navigate the crumbling tunnels, they encounter remnants of prior experiments: rooms filled with looping tapes, memory imprint chambers, and preserved logs of “Subject 8A” sessions that eerily mirror Iris’s life. Isla begins to break down under playback pressure, unable to distinguish memory from reality, while Cam is nearly lost to a feedback loop created by his own voice bouncing across the signal. At the facility’s center, Iris enters a sealed chamber built to house the original broadcast emitter, now pulsing with energy. She realizes that she is both the product and the failsafe—engineered, consciously or not, to complete the chain or sever it. The group pleads with her to fight the signal’s pull, but Iris steps forward and manually overloads the system, triggering a surge that short-circuits the broadcast and collapses the network. In the silence that follows, the town’s signals go dead, playback ceases, and for the first time in weeks, no one hears the voice. The episode ends with Iris waking up days later in the woods where it all began—alone, unsure if what happened was real, but with a faint ringing still echoing in her ears.

Production

Development

Dead Signal was developed as a serialized supernatural mystery drama with a grounded, psychological tone, drawing inspiration from works such as Stranger Things, The OA, and Dark. The concept originated from the idea of a Cold War-era broadcast experiment resurfacing decades later, told through the perspective of modern high school students slowly unraveling their town’s hidden past. Designed to blend teen drama with analog horror, conspiracy fiction, and slow-burn paranoia, the series focuses on signal interference, memory distortion, and identity fragmentation without relying on fantasy or traditional science fiction tropes.

The original premise centered on a group of teenagers investigating strange transmissions following a structural collapse at a long-abandoned research facility. The creators intended the series to explore themes of collective memory, technological residue, and the psychological effects of unseen systems of control. The fictional town of Briar Glen was chosen as the primary setting to allow for narrative flexibility and to evoke the isolated, decaying atmosphere essential to the show’s tone.

Production of the series emphasized analog-era aesthetics, with practical effects, vintage equipment, and dated technology used heavily throughout the set design and audio elements. The creative team intentionally avoided overt supernatural powers or visual effects, instead relying on sound design, atmosphere, and performance to create tension. The first season was structured as a closed eight-episode arc with a beginning, middle, and end, while leaving room for further exploration of the signal’s origin and long-term effects in future seasons.

The title Dead Signal was chosen early in development to reflect both the literal motif of corrupted transmissions and the thematic focus on memory loss, forgotten trauma, and disrupted identity. The name also served as a reference to the show’s core mystery—the possibility that something long thought dormant was never truly gone, only waiting to be heard again.

Writing

The writing of Dead Signal was heavily influenced by late-20th-century psychological thrillers, analog horror, and small-town mystery dramas. The series was conceived as a slow-burn narrative with an emphasis on atmosphere, character isolation, and the psychological effects of memory distortion. Rather than relying on conventional science fiction or fantasy elements, the writers grounded the story in plausibility—drawing from real-world conspiracy theories, Cold War-era broadcast experiments, and government secrecy to frame the supernatural elements as emerging from lost technology and corrupted data, rather than otherworldly forces.

Each episode of the first season was written to function as a piece of a larger mystery, gradually building toward an explanation of the Bellridge signal without giving clear answers until the final moments. The use of a nonlinear progression—blackouts, playback loops, and overlapping realities—was a deliberate narrative device meant to mirror the characters' own uncertainty and the breakdown of reliable perception. Internal rules were created to maintain consistency with the signal’s effects, such as how memory decay would manifest and how exposure would escalate over time.

Dialogue was kept minimal and realistic, with a focus on subtext and emotional restraint to reflect the psychological burden on the characters. The teenage protagonists were written as intelligent but flawed, dealing with trauma, alienation, and trust issues, rather than as genre-savvy archetypes. Writers also incorporated recurring motifs—like static, repetition, and forgotten spaces—to reinforce the series' core themes of lost identity and buried truth.

The writers approached the season with a tightly planned arc, ensuring that each character's descent into the signal’s influence had a narrative and emotional payoff. While the season ends with the resolution of the immediate crisis, the script deliberately leaves several questions open, allowing future seasons to explore the broader implications of the Bellridge experiment and its reach beyond Briar Glen.

Casting

Sophie Thatcher was cast in the lead role of Iris Ward, with the creative team citing her ability to convey vulnerability and quiet intensity as essential to the character. Known for her work in psychological and genre-driven roles, Thatcher was chosen early in the casting process to anchor the series’ emotional arc. Her performance was praised for capturing Iris’s gradual unraveling while maintaining a grounded, empathetic presence. Joining her is Jack Champion, who was cast as Luca Grayson, the introspective and technically-minded friend who helps unravel the mystery behind the signal. The creators were drawn to Champion’s balance of quiet intelligence and emotional sincerity, seeing him as a natural fit for the role. His performance brought depth to the character’s curiosity and underlying fear, grounding the show’s more abstract elements through a human lens.

Series co-creator and executive producer Freddie Goodwin explained that his goal with Dead Signal was to build a “realistic universe”—one where the strange and unexplainable exist not through fantasy or supernatural logic, but through grounded, believable distortions of reality. Goodwin emphasized his desire to explore horror and science fiction through a psychological and technological lens, stating that the most unsettling ideas are often the ones that feel plausible. By stripping away superpowers and overt science fiction tropes, Goodwin aimed to create a world where the mystery could sit just beneath the surface of everyday life, rooted in forgotten experiments, corrupted systems, and the fragility of memory.
