From the liner notes

Dan Bartlett (John Cusack) is a lovestruck teen who misses his plane to the Caribbean in this engaging comedy. He was to join sweetheart Lori (Wendy Gazelle) and her father Bill (Monte Markham) in the tropical paradise. Determined to get to the island, his efforts are stalled by three natives with a penchant for marijuana. After he shakes the stoners, Dan is captured by the pirate Mac MacClaren (Robert Loggia). He escapes the scurvy buccaneer only to land in jail on bogus charges. Dan later follows his sweetheart to a yacht where her family is being hijacked by another crook. Veteran funnyman Jerry Stiller provides comedy relief.
