In this spaghetti western, a murderous robber hijacks a payroll train, murders everyone aboard and then stashes his loot. A gunslinger decides he wants the money for himself and hatches an elaborate plot to get it. He lures the crook into a rigged poker game and afterward a gunfight ensues. The quick-drawing gunman makes short work of the robber, then teams up with an insurance agent to look for the hidden fortune. Unbeknownst to them, the robber had an ace up his sleeve.
