n the not too distant future, boxing has been banned and replaced by robot fighters in the ring. Sam "Steel" Kelly is a former boxer but now owns one of these pugilistic machines. Unfortunately his robot, which he's named Battling Maxo, is getting old and many of its parts are no longer available. Kelly is broke and is doing everything he can to ensure Battling Maxo can enter the ring as the promoter has made it clear there's no payment if there's no bout. When Maxo breaks down however, Kelly decides to takes its place.
