 A hot-tempered bandit, Pancho Vanilla, robs a Mexican bank and rushes to his hideout to count the loot. Speedy Gonzales, Mexico s fastest mouse, follows Pancho there, intending to return the money to the bank. He challenges Pancho to a duel and then speeds past him again and again, bringing every cent of the money back to the bank and causing a flustered and enraged Pancho to shoot himself in the feet.
