The machine turns him into his opposite - a mad scientist and supervillain bent on world domination called Dr. Otto. He plans to use his Gloom Beam to render all the computers that keep people's financial records and bank accounts useless which would make him the only one with access to all this dough. Bumbling hero Lance Sterling and his cautious sidekick Doris are sent to Dr. Otto's lair to stop him. There, they must face various scary alter egos of Dr. Otto as well as his manservant, Willie the Robot.
