Synopsis by Hal Erickson
Eccentric "Daily Planet" stringer Horatio Hinkle (Lucien Littlefield) invents a robot named Hero, which he uses to break up a jewel robbery. The disgruntled thieves decide to kidnap the robot and force Hinkle to reprogram it to help them commit their next few crimes. This, of course, is a contingency that Superman (George Reeves) hopes to prevent--but he may be too late to do so. Future Gilligan's Island costar Russell Johnson is rather surprisingly cast as the leader of the criminal gang.
