Mafia hitman Tommy Spinelli (Joe Pesci) is flying to San Diego with a bag that holds eight severed heads, which he’s bringing to his superiors to prove that some troublesome rival mobsters are permanently out of the picture. When his bag gets accidentally switched at the airport, Tommy must track down his duffel bag and the 8 heads it contains.

Peter loves his next door neighbour Erica and, on the advice of his grandfather, decides to camp out on her front lawn for the entire summer, or until she agrees to go out with him. His father is none too happy about the idea and refuses to let his son back in the house, even to get a change of clothes.

Furious that her late father only willed her his gloomy-looking mansion rather than his millions, Carrigan Crittenden is ready to burn the place to the ground when she discovers a map to a treasure hidden in the house. But when she enters the rickety mansion to seek her claim, she is frightened away by a wicked wave of ghosts. Determined to get her hands on this hidden fortune, she hires afterlife therapist Dr. James Harvey to exorcise the ghosts from the mansion. Harvey and his daughter Kat move in, and soon Kat meets Casper, the ghost of a young boy who’s “the friendliest ghost you know.” But not so friendly are Casper’s uncles–Stretch, Fatso and Stinkie–who are determined to drive all “fleshies” away.
