Una

Una Spencer goes to the warehouse manager Peter Trevelyan's office, catching him by surprise. This present-day encounter triggers flashbacks that reveal their shared past. The moment establishes the tense frame of the story.

Flashbacks reveal that Ray Brooks, Una's father's neighbor, groomed the 13-year-old Una for three months. They planned to elope to Europe, and Ray takes her virginity in a coast hotel room the night before they would travel. He leaves immediately after; Una, believing she was abandoned, wanders the streets distraught until police return her home.

Ray is arrested for his crime and serves four years in jail. This event ends their brief contact and sets the stage for Una's long period of isolation. The case's aftermath shapes Una's early sense of betrayal.

Una grows up feeling isolated and hurt as she tries to process the past. Her father becomes violent toward Ray in rage. Years later, Ray dies in an accident at home, removing any immediate reckoning.

Fifteen years later, Una lives with her mother and fills her nights with one-night stands. She cannot form lasting relationships because of the abuse she endured. The pattern of loneliness defines her social life.

Meanwhile, the man once known as Ray has become Peter Trevelyan, achieving career success and marrying a woman his own age. He has built a stable life and a public image. This contrast with Una's life fuels the tension when she confronts him.

Una spots Ray's photograph in a newspaper and travels to the warehouse to find his workplace. The pursuit signals her craving for accountability and closure. She arrives with unresolved emotions and a plan to confront him.

Ray brings Una to the warehouse locker room and confronts him about the past. Ray remains defensive, fearing that Una will damage his career or hurt him. He exits to attend a critical staff meeting, trying to control the situation.

In the meeting, Ray tells his coworkers that management wants him to generate a list of people to fire. He then disappears from the room as angry executives rage around him. The denial and evasiveness reveal how far removed he is from accountability.

Una and Ray quarrel and reminisce about their affair. Ray insists that he is not by nature a hebephile and that he loved Una. He explains that he didn't intend to abandon her, but needed a walk and a drink to clear his head before they would elope. They have sex, but Ray leaves abruptly.

Ray tells his coworker Scott to escort Una out of the warehouse as he fears the confrontation. Una then goes to Scott's flat, where she seduces him. The night deepens with shifting alliances and blurred boundaries.

Una claims to be 'Pete's' daughter and uses Scott to reach Ray's comfortable suburban home for a party. Scott accompanies her to the party where Ray's presence is felt. The lie about paternity adds another layer of deception to the night.

At the party, Scott discovers that Una's claim of being Pete's daughter is false, which shocks Ray. Yvonne hints that their marriage isn't entirely happy. Tension mounts as the group sizes up Una's intentions.

Una wanders upstairs into Ray's 13-year-old stepdaughter's room and lies on her bed. The stepdaughter demands an explanation for the intrusion, heightening the sense of exposure and judgment in the room.

Una leaves with Ray, Yvonne, and Scott trailing behind as the party's turmoil continues. Ray denies that he abused his stepdaughter and, in a cruel twist, kisses Una on the cheek. He notices Yvonne, the stepdaughter, and Scott watching, and a dejected Una exits into the night while Ray returns to his family.
