The Mouse Trap

Detectives Cole and Marsh attempt to interview Rebecca, a survivor of a recent massacre at an amusement arcade, so that they can learn who was behind the murders. Rebecca is reluctant and claims that they all will be killed if she tells them, but eventually begins to explain what happened. A while in the past, arcade employees Alex and Jayna are told by their boss Tim Collins to stay on a late shift due to a last-minute booking. Later, whilst watching a copy of Steamboat Willie on a film projector, he comes across a Mickey Mouse mask that begins speaking to him. Tim, in a trance, slowly puts the mask on. After Jayna leaves the arcade, Alex witnesses Tim wearing the Mickey mask as he chains up one of the exits. Worried, Alex attempts to flee but stumbles upon her crush Marcus and her other friends—Ryan, Paul, Jackie, Gemma, Danny, Marie, and Rebecca— as it is revealed the booking was arranged by them to throw a surprise birthday party for her. As the party gets into full swing, Ryan gathers everyone's phones in a bag and leaves them on a counter. Meanwhile, Paul and Jackie head into a jungle gym to have sex, where Mickey appears and attacks them with a knife. The rest of the group learn that the exits have been chained shut, and the phones have been stolen. They split up to look for Paul and Jackie, while Rebecca encounters Mickey, who is now able to teleport but is easily scared off by flashing lights. Mickey wounds Marie, but she manages to escape before he can kill her. She informs Alex and Marcus, believing Ryan is the one who attacked her since he is nowhere to be found. Alex then discovers that the lights and phone lines are down before she, Marcus, and Marie find the corpses of Paul and Jackie. Alex activates the arcade's fire alarm in order to alert emergency services but Mickey kills Gemma and Danny, teleports into the laser tag arena and slits Rebecca's ankle. Alex sees Jayna returning to the arcade, but is unable to warn her about Mickey before he teleports and kills her. She finds Marcus and Marie interrogating Ryan, making them realize he is innocent. Mickey then appears and attacks them. Alex uses a flashlight to distract Mickey as Marcus knocks him down with a baseball bat, but Mickey teleports away before they can finish him off. The survivors realize that they can use Mickey's light phobia to nullify his teleportation. They lure him into the jungle gym and activate the strobe lights, disorienting Mickey as they beat him down. However, Mickey manages to turn off the lights with telekinesis and teleports away; he reappears behind Alex and decapitates her before disappearing. Back in the present, the detectives refuse to believe Rebecca's story and leave her locked inside her cell. In a post-credits scene, Mickey arrives at the police station, frees Rebecca from her cell, and tells her that there are some people he wants her to meet. Rebecca smiles at Mickey and follows him.
