The Joker tries to steal the Batmobile! And the Elongated Man has a change of face!

The Joker, disguised as Mr. DeNil, gets a contract to make old-time comedies for film director Van-Van Laugh. The Joker then takes to committing crimes dressed up as famous silent film comedians and committing robberies while his crooks film the whole thing.

The whole ordeal naturally attracts the attention of Batman and Robin, who soon figure out the Joker's plot, which is an attempt to steal the Batmobile. The dynamic duo foil the Joker, and send him back to jail, but his movie still is much liked by Van-Van Laugh.
