MEN MAY BE FROM MARS, BUT BADDIES ARE FROM VENUS! There's a hot new outer space-themed nightclub in Gotham City, and who better to rob it than Catwoman, Ivy, and Harley? But there's more to this intergalactic discotheque than meets the eye(s), as the Sirens discover when they stumble headfirst into a plot to destroy the entire planet led by the club's owner--the alien despot Despero! I hope you have good insurance, Gotham City, because you're about to get wrecked. Special appearances by deadly DJs, hunky alien hotties, dancers dressed as aliens, mutant failures, one wild UFO, and lots and lots of fire!
