A little boy makes his bedtime an exciting adventure, as he imagines Batman preparing to fight crime in Gotham City.

Batman has been kidnapped by the Riddler! The crook has left behind one of his infamous riddles, addressed to Robin. If Robin can solve the puzzle, he will locate the Caped Crusader, but that first riddle leads to another. Then the Riddler turns off all the lights in Gotham City. What, Robin wonders, is the point? When will the riddles end? If the Boy Wonder cannot find his partner by the next sunrise, Batman will be gone forever.

Two-Face and Clayface team up to capture Batman and Robin, and crush them under a giant coin.

After escaping from prison, the Riddler uses clever clues to trap Batman and Robin inside a tyrannosaurus rex robot.

Poison Ivy uses a giant Venus Flytrap to break out of Arkham Asylum, but Batman figures out a way to turn the tables on Ivy and add her deadly plant to the collection of trophies in the Batcave.

One of the trophies in the Batcave is Mr. Freeze's freeze ray, which he uses to create a zone of intense cold around himself as he attempts to steal a valuable diamond necklace--and it is up to Batman to stop the supervillain.
