The four Rangers mission is to find out who has been raiding settlements, kidnapping skilled workers and killing the rest. Reese and Joe track the raiders for three days and are captured. Joe eventually becomes a gladiator second class and Reese a slave in the camp of Hannibal Rex, a would-be Roman-type emperor in Texas. Chad and Erik pose as a sculptor and an architect and are also abducted by Hannibal's henchmen. Hannibal's favorite wife Celeste invites Erik to her tent but he suspects a trap. Chad goes instead and is punished by being hung on a slowly heated metal pole that is suspended over a pit of poisonous snakes. Joe, Reese and Erik free Chad and they succesfully battle Hannibal Rex and his henchman. Erik ends up having a picnic with Celeste who he has handcuffed himself to.
