During Mardi Gras in New Orleans, agents West and Gordon look for the cruelest former commander of a Civil War prison who has been a fugitive from justice for the abuse of prisoners. They meet a young girl who leads them to Hazard, her legless father and victim of the prison commander. Hazard and his men are after the commander as well, but their real goal is to find a shipment of one million dollars that disappeared after arriving at the prison.
