Small-time Long Island criminal, Johnnie LoDuco, after giving up a promising career as a smut peddler, gets involved with some friends who rob a convenience store, get caught because they are too stoned to make a getaway, and then pin all the blame on him. And when his childhood buddy Vinnie bails him out of jail, he agrees to partake in a scam Vinnie has put together that will make them all rich. The only problem is: while out fishing one day Johnnie reels in the biggest catch of his life... Vinnie's head on the end of the fishing line. Now mafia types, bounty hunters, and Vinnie's girlfriend are after him, and Johnnie LoDuco doesn't have a clue as to why. Plus, they all seem to want Vinnie's head, but Johnnie seems to have misplaced it in an ice cooler—and if he wants to live he needs to get it back.
