Hank Mitchell has an apparently perfect small-town life, complete with steady job and a pregnant wife. The only cloud on his horizon is his half-witted brother Jacob and his redneck pal, who clearly resent him. The three of them stumble by chance on a crashed plane containing a charred body and $4 million in a bag. They decide to keep the money -- it is a victimless theft after all -- but the simple plan begins to unravel. The police become suspicious, Jacob talks too much, and events soon spiral out of control.
