Camp counselors Marcie and Jack (Kevin Bacon) sneak into a cabin at Camp Crystal Lake to have sex. Little do they know that the dead body of their co-worker Ned is in the bunk above them the whole time, although it's really the dude under the bed who'll ruin their fun.
After sex, Jack is impaled on an arrow pushed up through the mattress by Jason Voorhees. Marcie is interrupted while showering and takes an axe in the face. Not an Axe Body Wash—an axe.
