Red Rock West

Michael Williams (Nicolas Cage) is a drifter living out of his car after being discharged from the Marine Corps. A job on an oilfield falls through due to his unwillingness to conceal a war injury on his job application, so Michael wanders into rural Red Rock, Wyoming, looking for other work. A local bar owner named Wayne (J. T. Walsh) mistakes him for a hit man, "Lyle from Dallas", whom Wayne has hired to kill his wife. Wayne offers him a stack of cash—"half now, half later"—and Michael plays along by taking the money. Read more on Wikipedia.
