After Sunset was abducted by former bully Gilda and her cronies, Sunset in a delirious state due to a hit by a crowbar, thought the only way to escape from a giant bat creature would be to fall into a vat of Chemicals. However, this resulted in Sunset having Amnesia, so she couldn't remember Anon-A-Miss, what her classmates did to her, or her own name.

But soon she would meet other's who suffer with the same clownish affliction and they would form a little group called the Jokerz, a group of chaotic pranksters and criminals who are ready to spread through the streets of Gotham, with smiles on their faces.

Can Batman, and GCPD Captain Rainbow-Dash, stop this group before more mischief is made.
