The town is plagued with vice and injustice, headed by the corrupt Sheriff Layne Hunter, who learns where gold is located and wants to find it before the settlers.

Meanwhile, the three "bad men", tired of their life of crime, decide to arrange a marriage for Lee, who soon meets up with Dan.

The three outlaws must deal with that unexpected romantic attraction, along with the looming sheriff's gang and the race of the settlers' wagons for gold.

Dan and Lee are married, and have a son, named Stanley Costigan Allen O'Malley, in memory of the 3 Bad Men.

During the filming, three of the actresses involved, Olive Borden, Priscilla Bonner, and Grace Gordon, became ill with a form of paratyphoid fever, and had to be taken to the hospital.
