Innocent lives hang on the whim of an elusive psychopathic murderer whose strange riddles and impossible timelines force three people into a mission to end the game before one or all of them die.

While driving to Las Vegas for the bachelor party of her sister Melissa and her fiancé Bobby, Kayla stops the car in the gas station to meet her date, Nik, a guy she met on the internet. Nik convinces her to take a secondary road under the protest of Bobby but the car breaks down. They find a house in the middle of nowhere and decide to take the car parked in the house's garage to the next city, and return with a rented car to pay for the damages provoked by Nik; Melissa leaves her cell number. However, they discover that the owner of the place is the sadistic truck driver Rusty Nail and they have to pay a high price for what they did.
