Get ready for action as the Dynamic Duo, Batman and Robin, take on a Gotham City's underworld in three titanic tales. First off, in "The Secret of Mechanical City," a crook with a bunch of stolen military intelligence hopes to lose both his former partners in crime and the caped crusaders in a super-scientific theme park. Automated planes and giant sentry-robots that seemingly go mad prove almost too much for the Batman.
Then, in "The Mirage Maker," Batman and Robin can't believe their eyes as one fantastic disaster after another unfolds before them, allowing a fanciful thief to escape. Only by turning the tables of the illusionist, do Gotham's guardians prevail. Finally, in the strangest team-up of all, the Dynamic Duo get help from "The Bat-Ape." A gorilla, mistreated by his crooked handler, takes a liking to Batman and his cape and cowl. To free an innocent man, man, boy and ape take on criminals who are more animal than brave Mogo will ever be.
