Western action adventure in the best Italian tradition, Ace HIgh was shot in Mexico, Spain, and Rome. Cacopoulos (Eli Wallach) takes $300,000 from two hombres of questionable moral fiber, then proceeds to spread the cash around generously. His victims follow his trail, but when the men finally do meet, they must join forces to defend themselves against a murderous desperado. Before that battle is over, Cacopoulos has once again absconded with the cash. And the chase is on, leading them, ultimately, to a crooked Mississippi gaming house, a blazing gun battle, and lots of money for everyone.
