The film follows Harris, a man who prefers hooking up over actual relationships that meets a woman with an unpredictable temperament.
Harris is an average man who regularly uses an online dating service to seduce women into hookups and then proceeds to ghost them the next morning.
That night, he initially attempts to complete a project for work, but invites Riley over after she sends a nude image.
Upon returning home at the end of the day, Harris is shocked to discover Riley still in his apartment, cooking an apology dinner for him.
Harris is convinced Riley is responsible for him getting fired and for downloading the child pornography onto his computer and realizes that a confession is likely the only way for him to avoid prison time.
Riley apologizes for faking her suicide, but refuses to acknowledge hacking his Twitter account or downloading child pornography onto his computer.
Once Harris unties her, she attacks him, eventually gaining the upper hand and striking his head repeatedly with a golf club, apparently killing him.
He receives a call from his lawyer informing him that all charges have been dropped due to a confession by Keenan, the teenager from Harris's online video game whom he'd insulted.
[1] Owen Gleiberman of Variety said the film was "a toxic master of the digital hookup gets his comeuppance in a tawdry but watchable low-budget Fatal Attraction for the age of Tinder".
[2] John Defore of The Hollywood Reporter also compared the film to Fatal Attraction, saying it was a "nightmare of modern dating".
