Kenny is the protagonist of Shut Up and Dance. He is portrayed by Alex Lawther.
Kenny is a young man with brown hair and pale skin. He is shown to be rather weak and ineffectual.
Kenny returns home from his busboy job to find that his sister, Lindsay, has infected his laptop with malware; Kenny downloads Shrive, a purported anti-malware tool which actually allows an unseen hacker to use the laptop's camera to record him masturbating. The hacker emails Kenny, threatening that the video will be sent to everyone in his contacts list unless he follows a series of instructions.
The next day at work, Kenny receives a text directing him to a location 15 miles away, with only 45 minutes to get there; he frantically cycles to the coordinates. There he is met by Moped Man, also acting on instructions from the hacker, who gives Kenny a box with a cake inside. Kenny is instructed to deliver the cake to a Wayhaven hotel room, where he finds Hector. Hector then receives blackmail messages of his own: he was about to cheat on his wife with a prostitute, and follows the instructions out of fear he will lose custody of his children.
Kenny and Hector are instructed to drive to a location outside the city. However, when they stop for petrol, Hector's wife's friend Karen asks Hector for a lift home, for which they must drive recklessly without explanation, before continuing to their destination. There they are told to use a gun concealed in the cake to rob a branch of National Allied bank. Hector insists on being the driver, leaving Kenny to perform the robbery. Though Kenny urinates out of nervousness during the robbery, he manages to get a bag full of cash and flee the scene with Hector.
Hector is told to destroy the car, while Kenny carries the money to a drop-off point in a nearby wood. There he meets another blackmail victim, who explains they are to fight to the death while the blackmailer observes through a camera-equipped drone; the money goes to the winner. Kenny tearfully protests that he merely looked at some pictures, but the man guesses that – like him – it was child pornography. Kenny brandishes the gun, then attempts suicide, but finds the gun isn't loaded. They fight hand to hand, as the drone transmits.
Some time later, Kenny staggers from the woodland with the money, bloody from the fight. He receives a hysterical call from his mother; the video of him masturbating to pictures of children is now public. He ends the call as the police arrive, offering feeble resistance as they apprehend him.
