After a hard day of volleyball at the beach, a teen whose parents are away decides to have a slumber party with her girlfriends. Their boyfriends predictably show up to scare them, but a stranger from the beach is also seen lurking around the house. Soon the group begins experiencing an attrition problem.
Unfortunately the movie Slumber Party Massacre III is not yet available on Disney Plus.
