One of the tribesmen crafts a clay piñata which the tribe put their evil into, and then sends the object afloat in the ocean.

A group of college students sail to a remote island for an annual Cinco de Mayo treasure hunt.

The groups consist of Jake and Julie, Doug and Carmen, Bob and Lisa, Larry and Connie, and Kyle and Tina.

A new group of Kyle, Tina, Doug, Carmen, and Lisa now leaves when they see Bob ripped in half on a tree.

Originally, the piñata monster was played by an actor in a rubber suit, and the film contained no computer effects.

[citation needed] Bruce Eder of Allmovie praised the film's evoking of numerous horror films from past decades, and said, "The plot is clever, turning logic on its head in grisly fashion and twisting around some of the conventions of the modern horror genre."
