Wonder Woman, Batman, Robin and Green Lantern guard the Astro Chemical Research Plant, as the scientists work on a new energy source called "liquid light", which can dissolve nearly anything on Earth. Unfortunately, Brainiac, Cheetah and Scarecrow are nearby, and they have a scheme to steal this powerful new chemical. First, they surprise the four superheroes by swiping their power devices (Wonder Woman's lasso, Batman and Robin's utility belts and Green Lantern's power ring), and then take off. Next, the Hall of Doom appears in the sky and beams the three SuperFriends aboard. Once on the ship, Lex Luthor presides over a mock trial of the foursome. They are found guilty of upholding the law and sentenced to fight Brainiac's android replicas of themselves - androids which have the advantage of possessing their own power devices. Meanwhile, Black Manta and Bizarro steal the liquid light, as Superman, Flash and Black Vulcan attempt to stop them.
