 Boulder, a thug, is recruited to participate in a scheme. Bouler undergoes plastic surgery to look like Superman and then is trained by a voice coach to sound like him. Wearing a Superman costume with a bullet-proof vest underneath, he intimidates merchants and others into giving up money. Yet, Boulder s boss has the bogus Superman donate the stolen money to charity. All of this causes great concern to Clark Kent, who s unsure whether he might be sleepwalking or not. Clark gets reassurance when he finds out the phony Superman makes an appearance while the reporter was elsewhere. Now, the real Superman intends to put an end to this caper.
