Before Arrow returns with Season 3 in October on The CW Network, fans can check out star Katie Cassidy in a completely different role in the first trailer for The Scribbler. The actress stars as Suki, a young woman who tries to cure her multiple personality disorder by using a machine known as The Siamese Burn, which is designed to remove her other troubling personalities, as she faces an identity crisis about who she really is.

Kunal Nayyar, Eliza Dushku, Sasha Grey, Michelle Trachtenberg, Gina Gershon, Michael Imperioli, Garret Dillahunt and Billy Campbell co-star in director John Suits' graphic novel adaptation, which debuts on iTunes and VOD formats September 19.

The Scribbler follows a troubled young woman named Suki (Katie Cassidy) who confronts her destructive mental illness using an experimental machine called "The Siamese Burn" which was designed to eliminate multiple personalities. But as Suki gets closer and closer to being "cured," she's haunted by a disturbing thought-- what if the last unwanted personality remaining actually turns out to be her true identity?
