Linda Lawrence June Lockhart is attacked by a ski-masked intruder in her rural home, and pushed from a second-story window to her death. Her sister, Clarissa "Keegan" Lawrence Jo Ann Harris, a successful journalist, returns to their hometown upon the shocking news. The death is investigated by police officer Roger Lane Sam Groom, who wrestles with whether it was an accident, suicide, or a deliberate murder. The case threads through small-town life as Keegan reconnects with old friends at a local diner: Mary Adams Denise Galik, Chris Howlett Christine L. Tudor, Carol Bailey Robin Hoff, Randy Colleen Camp, and Sooty Lane Jere Rae Mansfield, who—like Roger—were all part of their high school cohort. Sooty is married to Roger, further entwining the threads of past and present.
Back in town, Keegan visits their estranged mother, Marge Lawrence, June Lockhart and then heads to a flag football game with her old circle. Among the familiar faces sits a brooding newcomer, Billy Owens Steve Railsback, a Vietnam War veteran who carries the weight of his injuries. Billy now works at the local cinema, where he changes film reels, and he has formed a quiet but intimate bond with Roger through their shared service. The movie theater becomes a pressure valve for the town’s secrets, a place where fear and memory mingle with the reel-cutting and whispers of the past.
At a pool party that night, romance and jealousy collide. Roger discovers Randy kissing another man, and a volatile argument ensues. Randy rebuffs him, insisting their relationship is casual and not bound by loyalty. The party ends in tragedy when a ski-masked attacker drags Randy to the bottom of the pool, binding her legs with wire and anchoring her to a grate, effectively drowning her. The news of Randy’s death ripples through Keegan’s circle, and Chris—who has also had a complicated entanglement with the same man—confides to Keegan that Linda and Randy were involved with the same mystery man, though she stops short of naming him.
Roger invites Keegan to his home, and the two go to a film after Roger’s shift at the theater, with Billy joining them sporadically. A fragile romance begins to blossom between Keegan and Roger, deepening Keegan’s divide between the truth she seeks and the danger that swirls around her. The danger intensifies when Chris is attacked in a parking garage by the killer, who manages to strangle her unconscious, but is interrupted when two lot attendants arrive. The killer remains at large, and fear spreads like a shadow over the town.
In a chilling confession, Roger reveals to Sooty that he is the killer, and he strangles her to death. The pattern continues as Chris is attacked again late at night while driving, and she escapes on foot into the woods, stumbling into an overgrown cemetery before the killer captures her and buries her alive in a grave. The killer’s identity shakes Keegan to her core, even as she tries to piece together who is orchestrating these murders.
Meanwhile, Roger appears to relish the slow, intimate thrill of his crimes, recounting to himself in a theater basement how a moment of fear evolved into a fatal impulse that pushed him onto a path of murder. Keegan, ever observant, checks the theater, hoping for a sign from Roger. When he fails to show for a date at a restaurant, she follows the unsettling hush of the theater basement.
There she confronts a terrifying truth: Roger is the killer, and a tense confrontation unfolds in the dim corridors of the cinema. Keegan shoots him to stop the spree, and Billy emerges from the shadows, trailing through the theater basement. He chastises Keegan over an intercom for killing Roger, a man he had considered a friend. The lights flicker and go out, and in a final burst of danger, Billy swings down from the rafters toward Keegan, attempting to finish what the killer began.
Keegan’s struggle culminates in a chilling sequence among mannequins and a maze of props in the theater. She discovers Sooty’s corpse lying among the figures, recoiling in horror as she races to escape upstairs. On the stage, Billy’s voice booms through the intercom, scolding Keegan for her actions and challenging her to survive the night. The room goes suddenly dark, and a perilous confrontation explodes in a deadly struggle between mother, sister, and killer beneath the flickering lights of the cinema. The film closes on a note of looming danger, where trust is shattered, and the line between protector and predator blurs in the shadows of the screen.
