Trading in his white hat for a black one, Arness plays a bandit. He and partners Robert J. Wilke and Don Megowan pull off a robbery; the partners then vamoose with the loot, leaving Big Jim empty-handed and seriously wounded. He is also betrayed by his lady friend Angie Dickinson.
When Arness finally catches up with his former chums, he decides to "psych" them out rather than fill them full of lead right off the bat.
