[2] Joe and Averell are respectively the oldest and youngest of the four Dalton brothers, the most dangerous bandits in the history of the Far West, and their failures are of such calibre that their own mother is turning against them.

But they react when Mama Dalton kicks them out of their own home and they decide to make her proud of them by robbing the Gulch City Bank, where security is so high that even employees are trained in martial arts.

Joe immediately decides to get the hat, so the four brothers run away from prison and head for Mexico, leaving chaos in their wake.

Arguing non-stop, Joe and Averell compete for power in a small town and manage to infiltrate a gang of criminals, where, after a spectacular battle, they steal the magic hat from the bandit who had it.

But the problems are only beginning because of the constant and growing rivalry between Joe and Averell and the fact that the law is on their heels.
