Kenny (
Alex Lawther) returns home from his restaurant job to find that his sister Lindsey (Maya Gerber) has unintentionally infected his laptop with
malware. He accidentally downloads an anti-malware
trojan, which allows unseen hackers to record him masturbating through his
webcam. They contact the adolescent, threatening to leak the footage if he refuses to comply. At work, a text summons Kenny to a location away in 45 minutes. Feigning illness to leave, he frantically cycles there and is met by another blackmail victim (
Ivanno Jeremiah), who passes Kenny a box containing a cake. Ordered to deliver the cake to a hotel room, Kenny meets Hector (
Jerome Flynn), whom the hackers also contact. He had arranged to commit adultery with a prostitute and fears he will lose custody of his children if his wife Penny (
Leanne Best) finds out. The two are told to drive to a set of coordinates. Stopping for petrol, they meet Karen (
Natasha Little), a friend of Hector's wife, who requests a lift home. Hector drives recklessly in order to get her there so that he and Kenny can then continue to their destination to meet the strict deadline. Tasked with using a gun concealed in the cake to rob a bank, Hector insists on being the driver, leaving Kenny to perform the robbery. Despite urinating in his panic, he steals a bag of cash and flees the scene with Hector. Hector is instructed to destroy the car, while Kenny takes the money to a drop site in a forest in
Wittenham Clumps. He meets another victim (
Paul Bazely), who explains they are to fight to the death while being filmed through a drone, and the winner earns the money. Kenny's opponent deduces that, like himself, Kenny has been targeted by the hackers for being a
pedophile. Kenny attempts suicide, but discovers the gun from earlier is empty, and the other man attacks him. Arriving home, Hector is texted a
Trollface, learning the blackmailers have disclosed evidence of his infidelity to Penny regardless. The others' information is also released. A shellshocked Kenny staggers from the woods, injured and traumatized after the fight. His mother (
Camilla Power) phones him, shocked and disgusted that he has been "looking at kids" as seen in a video watched by Lindsey and her friends. As she begs Kenny to tell her none of it is true, he hangs up, also receiving a trollface image as police arrive and apprehend him. ==Production==
