College sophomore, Margot, works at a local movie theater. Her roommate, Taylor, moderates a feminist subreddit called "The Vagenda", and tends to see the worst in men. Margot begins dating a frequent visitor of the movie theater, Robert. Margot begins to imagine Robert violently attacking her.

After their first official date, Robert learns Margot is only 20. They are turned away from a bar and return to his house to have sex. Throughout the encounter, Margot speaks to a second version of herself. Her other self tries to convince her to tell Robert she changed her mind. Instead, Margot has sex with him and fakes an orgasm, telling her other self she is afraid of violent retaliation. She finds out Robert is 33, and notes that the house has no sign of the cat he mentioned in his texts.

Margot debates whether or not to ghost Robert and imagines him dying in various ways. Taylor steals Margot's phone and texts him "I'm not interested please stop texting." Robert initially takes this well, but later sends Margot a barrage of misogynistic messages and calls her a whore.

Later, Margot realizes Robert is following her. She reports this to the police, who say he technically is not breaking the law, but advised to contact the reporting officer if she has more solid evidence. Margot considers buying a taser, and the salesperson suggests she buy a gun. She ends up buying tracking devices to see if Robert is actually stalking her.

While planting the tracking device in Robert's car, she comes face to face with a dog, the same dog she saw inside the dorm in the beginning of the film. She realizes that Robert had been following her before they met. Robert hears the commotion and comes into the garage to investigate, discovering Margot. Margot gets sprayed with pepper spray and hits her head on the garage floor, leaving her unconscious.

When she regains consciousness, she finds herself inside Robert's house. Robert explains that he stalked her before they began dating, and they begin to argue. He planned to drug Margot to induce memory loss and drop her off at her dorm, out of fear that if she escaped, she would alter the story to be in her favor, which could possibly lead to Robert getting arrested. Margot tries to escape, but Robert drags her back inside and a physical struggle ensues.

During the struggle, Margot opens a door that leads to the basement, and a cat escapes, which means Robert did not lie about having cats after all. They continue to fight and they both end up falling down the basement stairs. During the fall, a space heater is knocked over and starts a fire. Robert climbs into his house's cistern to avoid the flames and Margot hesitates before joining him. Both survive the fire.

Margot wakes up in the hospital and eventually recovers. She was told Robert left town and did not leave a way for anyone to contact him. After Margot returns to work at the movie theater, a new man hits on her in the same way Robert did.
