The Last of Sheila (1973)

Any number can play. Any number can die.

A year after Sheila is killed in a hit-and-run, her multimillionaire husband invites a group of friends to spend a week on his yacht playing a scavenger hunt-style mystery game—but the game turns out to be all too real and all too deadly.
