Friday the 13th

In 1958 at Camp Crystal Lake, camp counselors Barry and Claudette sneak away from other counselors for a late night rendezvous in a supply shed. An unseen assailant attacks and murders them.

On Friday, June 13, 1979, camp counselor and cook Annie hitchhikes with truck driver Enos toward the reopened Camp Crystal Lake. Enos warns her about the camp's troubled past, beginning when a young boy drowned in Crystal Lake in 1957. After Enos drops Annie off at a crossroads, she hitches another ride from an unseen person driving a Jeep. After the driver passes the camp entrance, Annie becomes fearful and leaps from the vehicle, fleeing into the woods where the driver eventually slashes her throat.

Counselors Ned, Jack, Bill, Marcie, Brenda, and Alice arrive at the camp. Alice, along with owner Steve Christy, refurbish the cabins and prepare for incoming campers. As a thunderstorm approaches, Steve leaves for supplies. Ned sees a cloaked figure walk into a cabin and follows. Later, while Jack and Marcie have sex, they are unaware of Ned's dead body above them in the bunk bed. When Marcie leaves the cabin for the public bathroom, the killer pierces Jack's throat with an arrow before following Marcie into the bathroom and killing her with an axe. After playing strip Monopoly with Alice and Bill, Brenda returns to her cabin. She is lured outside by a little boy's voice calling for help and ventures toward the camp's archery range, where the floodlights suddenly turn on and she is attacked offscreen by the killer.
