When some badly dubbed bad guys rob a shipment of gold from a railroad company, Mike Sturges and his brother are framed for the crime.  Thrown into the hellish Yuma State Prison, the brothers are tortured and forced to work hard labor.  The torture is so intense that Mike's brother ends up dead, nailed to a cross!  Mike escapes from prison and goes after the bad guys who framed him, and to also settle the score against the prison guard who was responsible for his brother's death.  It's hot times in Yumatown tonight!  The wild west will never be the same as muscles vs. pistols in this action-packed spaghetti western!
