WGN America has released the full-length trailer for Season 3 of Salem, in advance of the Salem panel event at this year’s San Diego Comic-Con. The third season is set to premiere on Halloween week this year. The trailer announces that in Salem Season 3 “Everything in Salem has gone to Hell!”

The third season dawns with the triumph of the witches’ plan to remake the New World by bringing the devil to earth and making Salem his capital.  But the devil is a liar, and instead of a New World free from murderous Puritan hypocrisy, his own plan will bring nothing but death and slavery with the ultimate aim of leading humanity to destroy itself.  And there’s only one person on Earth who can beat the devil — the very witch that birthed him, his mother, Mary Sibley.  The only problem is — she’s dead.  Or is she?

The cast and producers will reveal an extended sneak peek at the upcoming season during the SDCC panel. Series stars Shane West, Janet Montgomery, Seth Gabel, Iddo Goldberg and Elise Eberle along with executive producers Brannon Braga and Adam Simon will unveil footage from the series during a moderated discussion followed by an audience Q&A.
