Paranoid

Chloe takes the catwalk at a high-profile fashion show, soaking up the spotlight as the cameras flash. She later returns home to Toby and recounts having a great time in New York. A phone rings in the quiet house with no answer, making her decide she should change her number.

Back at home, Chloe tells Toby about New York and how great it was. The unanswered call lingers in the room, unsettling her and prompting a plan to change her number. The moment sets a tone of secrecy around her relationships.

At a photography shoot, Chloe runs into Ned, who is her other boyfriend. He casually offers to take her to a reunion of his former band, hinting it will be a memorable night. She agrees, moving toward the possibility of a new twist in her social circle.

Chloe lies to Toby, telling him she will visit someone in Brighton, a fabrication intended to cover her tracks. The lie deepens her web of deceit and fuels the upcoming tension. She also prepares for the night ahead without fully understanding what awaits.

During the drive to the reunion, Chloe falls asleep from the pills she took. She wakes up to the unfamiliar surroundings of the gathering and realizes she has arrived at the event against her will. The night begins with a sense of disorientation and danger.

Chloe meets Stan, his wife Rachel, their deaf daughter Theresa, and his brother Gordon, who films the party. Ned's wife Eve arrives and behaves rudely, cutting Chloe's hand on a glass. Eve quietly voices a malicious wish that Chloe should bleed to death.

Stan finds Chloe outside and says everyone else has gone, so she can stay the night. Inside, Rachel questions Chloe about photoshoots, and Chloe admits she simply pretends during them. The atmosphere grows tense as the household guards its own secrets.

Graham places the handcuffs Ned gave Chloe on the bed, signaling trouble ahead. Later, Stan drugs her and she drifts into an uneasy sleep. The sense of being controlled tightens as the night deepens.

Chloe wakes to find herself handcuffed to the bed in the basement. Clive, the silent stalker, continues to phone her. Theresa finds the tapes and drafts a police poster, but the authorities dismiss the concerns as a joke, while Gordon watches the footage.

Chloe slips free and escapes through the window, fainting outside when she spots Stan in a car. The outside world feels both dangerous and beckoning as she fights to survive. The escape marks a turning point in the captivity.

Clive makes his way toward the house, only to be shooed away by Rachel. He phones Chloe and hears that the shed phone is still ringing, which prompts him to decide to contact the police. Inside, Theresa remains unable to free Chloe, and Ned presses for a plan to preserve their actions on tape.

The group debates making a tape of Chloe enjoying herself to cover their tracks if she talks to the police. Ned, Rachel, and the others push this disturbing idea forward, increasing the sense of moral rot beneath the surface.

Theresa crashes through a window to attract attention as the police arrive, and Ned ushers Theresa toward a police car. Clive circles back and the police arrest Stan and his brother, breaking the immediate danger posed by the twisted scheme.

Chloe returns home, calling Toby as a final connection to normal life. The call ends with a chilling reveal: Toby is actually another stalker lurking behind the facade. The film closes with Chloe still surrounded by looming threats.
