Now officially called Supernatural: Bloodlines, this new take on the mythology of The Winchester Brothers will kick off with an episode of Supernatural on April 29. Supernatural: Bloodlines will follow the mafia-esque monster families that run the underbelly of Chicago, and are currently being tracked by a newly minted hunter.

Also in the cast are Danielle Savre as shapeshifter Margo Hayden, Sean Faris as werewolf Julian Durant, Lucien Laviscount as police academy trainee and newly minted hunter Ennis Roth, and Stephen Martines as Chicago detective Freddie Costa.
