chunk: A group of college friends consisted of Harvey, Nikki, Rob, Skip, Nan, Chaz, Kit, and Archâgather, celebrate spring break by spending the weekend at the island mansion of their friend and Skip's sister Muffy St. John, on the weekend leading up to April Fools' Day. The tone is set almost immediately with Muffy preparing details around the house, and finds an old jack-in-the-box she remembers in a flashback sequence. Meanwhile, her friends are joking around on the pier, then on the ferry to the island. When en route to the island, local deckhand buck Buck is seriously injured in a gruesome accident.
