No Country for Old Men (2007)

While out hunting, Llewelyn Moss (Josh Brolin) finds the grisly aftermath of a drug deal. Though he knows better, he cannot resist the cash left behind and takes it with him. The hunter becomes the hunted when a merciless killer named Chigurh (Javier Bardem) picks up his trail. Also looking for Moss is Sheriff Bell (Tommy Lee Jones), an aging lawman who reflects on a changing world and a dark secret of his own, as he tries to find and protect Moss.
