Bank Job — Steve Brewer

Jaded, rage-laden, and utterly stupid, brothers Leon and Junior Daggett and their homicidal partner, Roy Wade, entertain themselves by knocking over liquor stores and gas stations. When a run-of-the-mill robbery goes sour, they find themselves bloody and knocking on the door of a stranger for help. That stranger ends up being Vince Carson, retired bank robber.
Thinking they've discovered their big-time score, Leon and Roy take Vince's wife hostage, forcing him to rob the local bank in exchange for Maria's safe return. But Vince has other ideas. He sets out to prove that old age and treachery always triumph over youth and ineptitude.
