The first full trailer for “Supernatural” season 10 has been released, and with it, a first look at the demonic iteration of Dean Winchester (Jensen Ackles) as he sleeps, slugs and sings (?!) his way across the country, leaving chaos in his wake.

But Sam (Jared Padalecki) isn’t far behind his wayward brother, and he’s determined to steer Dean back onto the righteous path before King of Hell Crowley (Mark Sheppard) can lead him even further astray.

“Supernatural” returns to The CW on Tuesday, Oct. 7 at 9 p.m. To celebrate its tenth year and upcoming 200th episode, the network will air a retrospective special for the veteran series at 9 p.m. on October 6.
