Sleepaway Camp

In 1975, John Baker and his partner Lenny take John's children Angela and Peter on a boating trip near Camp Arawak. Angela and Peter prank their father by capsizing their boat. They attempt to swim ashore where Lenny is waiting for them, but camp counselor Mary Anna recklessly strikes John and one of his children with her speedboat, leaving just one of John's children alive.

Eight years later, Angela now lives with her eccentric aunt, Dr. Martha Thomas, and Martha's son Ricky. Aunt Martha sends Angela to Camp Arawak for the first time, along with Ricky, who had attended the camp before. Angela's introverted nature makes her a target for ridicule and bullying, mostly from her bunkmate Judy and their counselor Meg. Angela's other counselor Susie and the camp's head counselor Ronnie do what they can to help.

A cook, Artie, attempts to molest Angela, but Ricky catches him, and Ricky and Angela run out. Later, an unseen figure causes Artie to knock over a pot of boiling water and scald himself. Camp owner Mel Costic calls it an accident.

When campers Kenny and Mike mock Angela, Ricky and his friend Paul fight them. Paul befriends Angela. When Kenny drowns, his death is ruled accidental at Mel's insistence, although Ronnie and police officer Frank express doubt. Paul asks Angela to attend a film with him. After campers Billy and Mike throw water balloons at Angela, Billy is stung to death when someone traps him in a bathroom stall and drops a hive of wasps in it. Mel suspects a killer is in the camp.

Angela and Paul's relationship is strained when Paul kisses her. Angela has a flashback to when she and her sibling witnessed their father in bed with Lenny. The flashback goes further showing both one the siblings pointing to another whilst in bed. At this point, Angela wakes up from the flashback and recoils from Paul's advances and runs away. Judy seduces Paul and Angela finds them kissing. Paul attempts to explain himself to Angela at the lake, but Judy and Meg shoo him away and throw Angela into the water. After Ricky rescues Angela, children fling sand at them. Ricky comforts Angela and swears revenge on her aggressors.

Meg is stabbed to death in the shower while getting ready to meet Mel. At that night’s social, Paul apologizes to Angela and she asks him to meet her at the waterfront later. Mel finds Meg's body and is convinced that Ricky is the killer. The children who threw sand at Angela and Ricky are camping in the woods with their counselor Eddie when two of them ask him to take them back to the main camp. He returns to find the four remaining children hacked to death with his hatchet. Back at the camp, the killer enters Judy's cabin and murders her, raping her with a hot curling iron while smothering her with a pillow. The camp is thrown into a panic. Thinking Ricky is the killer, Mel beats him mercilessly, only to be shot in the throat with an arrow by the real killer.

Frank is called and searches with the counselors for the missing campers. Paul is at the beach with Angela, who suggests they go skinny dipping. Frank discovers Ricky unconscious but alive. Ronnie and Susie find Angela sitting on the beach and humming, with Paul, whose head appears to be resting on her lap as she strokes his hair.

A flashback shows Aunt Martha welcoming the survivor of the boat accident into her home. It is revealed that Angela died in the accident, Aunt Martha took custody of Peter, and she raised him as a girl. Back in the present, "Angela" leaps to their feet holding a hunting knife, allowing Paul's severed head to fall on the ground. "Angela" stands nude and blood-covered before the horrified Susie and Ronnie and growls like an animal. 

Slightly disturbed and painfully shy Angela Baker is sent away to summer camp with her cousin. Not long after Angela's arrival, things start to go horribly wrong for anyone with sinister or less than honorable intentions.

Angela Baker, a shy, traumatized young girl, is sent to summer camp with her cousin. Shortly after her arrival, anyone with sinister or less than honorable intentions gets their comeuppance.
