Men with Guns (1997)

Three losers, Eddie, Lucas and Mamet, are sent to collect some debt at a remote farm. But the thugs there are too hard for them, and they are humiliated. They return for revenge, it gets out of hand, ends with a bloodbath and they are left with a big amount of cocaine. The drugs belong to local mob boss Horace Burke, who sends his son to find them. Cops are also after them.
