Based on the urban myth that you can breathe in evil spirits when passing cemeteries, Hold Your Breath follows seven friends embarking on a weekend camping trip who pass a run-down cemetery and find themselves arguing about the legitimacy of the urban myth. When one friend refuses to hold his breath while passing by, he finds himself the unwitting host to a notorious serial killer who jumps from body to body in order to pick off each of the friends one by one.
