Larry, who is awaiting a large inheritance, lives with his uncle who hopes to receive part of the hefty sum. He meets another specimen of its kind, weak, lazy and eager to show off, who lives on the hooks of an elderly woman. The two thugs sympathize and cause, by game, a fatal accident. From perverse games to silly games, they enter a deadly spiral.
