Sara and Demi Meet Batman

Two girls are locked into Arkhan Asylum, one being the child between the Joker and Harley Quinn and the other with an electrifying personality. The girls are forced to bunk in Wayne Manor until they clean up their acts before they are destroyed in a matter of time. Demi finds a bond between Mr. Bruce Wayne and Sara finds herself having a ball with Dick Grayson. I suck at summaries!
