Synopsis:
Joker takes up operation in Metropolis bringing him to the attention of Superman. When the Harlequin of Hate makes an appearance at an outdoor exhibition, the Man of Steel is there to stop him. Joker, however, is now teamed with Luthor. Lex uses an atomic disperser to transform Superman into an electronic stream. Batman and Robin arrive too, but the crooks escape.

The Joker-Luthor team strikes again at a flower exhibition. Again, Superman is transformed and Batman is unable to defeat the villains. When the crooks strike a third time at a gem expo, Superman has figured out their plan. Luthor has disguised himself as the Master of Ceremonies in order to steal the gems. Superman deduced that the previous robberies were designed to photograph the MC, so Luthor could impersonate him. With the plan exposed, the villains are caught and the robbery prevented.
