The Man With No Name and Tuco are gunmen who admire each other professionally but dislike each other personally. Encountering a group of dying soldiers, Tuco learns the location of the graveyard where a Confederate treasure is buried, while the Man With No Name learns the identity of the exact grave.
Joined by mercenary drifter Sentenza, they cross the desert, each of the desperadoes knowing part of the secret and each focusing his squinty eyes on the $200,000 bounty.
