In 1975, John Baker and his boyhood friend 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. However, Mary Anna, a counselor at the camp, recklessly strikes John and one of the children with her speedboat. Delores, a water skier, screams for help.
