When a burglary of S.T.A.R. Labs leads to theft of a secret file by the terrible duo of Poison Ivy and Floronic Man (Jason Woodrue), crime and disorder have carte blanche. While the Dark Knight and Nightwing are conducting their investigation, they are trying to get the help of some free electron: Harley Quinn! Recently released from the Arkham Asylum and busy getting acclimatised to his new life away from the spotlight reserved for super-wicked, Harley finds himself once again donning his costume and shouting. So sit back comfortably while Kevin Conroy, Melissa Rauch and Loren Lester shine amongst a stellar cast in this action-packed adventure, high-speed pursuits and nasty brawlers who may even see Batman having fun!
