Sam and Buddy, two highway robbers, join with Colonel Quint, a big crook, who sold his services to Morgan, the banker, in order to free Baby, the banker's daughter, abducted by Espartero and his killers gang. A plan to 'sell' fake dollars to Espartero goes awry, but the two sons of the forger join Quint, and so does Mokaiko, a brave Japanese cook. The rag-tag band of Quinlan meets Espartero in several scraps, and then a climactic confrontation. All are ugly, bad, and dirty (except Baby), and fight accordingly.
