Will Cannon hears about a gang of outlaws operating out of the small village of Pecos, New Mexico. Moses, the leader of the outlaw gang, claims he is the “Robin Hood of New Mexico”. The outlaw boss says he will take all of the land given to the Mexican people in land grants by the King of Spain. Other outlaws have made such a claim in the past and all of those outlaws failed to claim one acre of land but the outlaws did find some people willing to join their cause. Will and his brother, Joe Cannon, are interested in building a saw mill near Pecos so Will rides to Pecos to confront the outlaw gang.
