You Might Be the Killer is a 2018 American supernatural slasher film directed by Brett Simmons and written by Covis Berzoyne, Thomas P. Vitale, and Simmons, based on an idea by Chuck Wendig and Sam Sykes. The film stars Fran Kranz and Alyson Hannigan, and features Brittany S. Hall, Patrick Reginald Walker, Keith David, and Bryan Price in supporting roles. Plot While in a panicked state at Camp Clear Vista, lead counselor (and camp owner) Sam calls his friend Chuck (short for "Charlotte"), a horror movie enthusiast working at a comic book store. Sam explains that a masked murderer is loose on the campgrounds and has killed "a lot" of counselors. Chuck asks Sam for more details. Sam begins recounting his first day at the camp with fellow counselors including Carol, Ted, Steve ‘The Kayak King,’ Drew, Alice and Heather, Sam's ex-girlfriend Imani, Freddie, Nancy, Brad, and Jamie. Sam suffers a momentary blackout while on the phone with Chuck. Sam escapes the cabin where he is hiding when someone sets it on fire. Sam briefly encounters the masked killer before finding a new hiding spot. Chuck calls back to help Sam deduce the killer's identity. Sam recalls how he and several other counselors found themselves trapped at the camp after discovering several dead bodies. A flashback shows Sam stumbling upon Freddie and Nancy while patrolling the woods for the killer. For some reason Freddie and Nancy are unable to hear Sam. Sam begins suffering a blackout as he witnesses the killer slaughtering them. Sam and Chuck eventually conclude that because he is covered in blood, holding the killer's signature blade, and possesses a mysterious wooden mask, Sam may actually be the killer and his blackouts prevented him from remembering. Sam tries to destroy the mask, but discovers it is unbreakable. He then attempts to burn the mask, only for his face to burn as well. Chuck theorizes that the mask may have imprinted on him. Fearful that the surviving counselors are going to kill him, Sam goes back into hiding. Chuck asks Sam to remember how everything started. Sam flashes back to killing skinny-dippers at a pool, a couple in a kitchen, and then his friend, Steve "The Kayak King," while possessed by the mask. Sam recalls telling Camp Clear Vista's haunted history to other counselors around a campfire. Sam tells the tale of a woodcarver who crafted a mask
