Synopsis:
Bruce Wayne and Dick Grayson witness the crash of an alien space capsule. They enter the capsule where an explosion turns their skin green. The strange condition prevents them from operating as Batman and Robin, so they make up a story about the Dynamic Duo becoming radioactive and forced to wear bandages.

The mummified Batman and Robin patrol Gotham, successfully protecting their secret identities. Vicki Vale is not convinced, so the heroes are forced to carry out the charade even after the effect has worn off in order to keep their secrets concealed.
