Sam & Dean Have Work to Do in 'Supernatural' Season 15 Trailer (PHOTOS)

The past is back to haunt Sam (Jared Padalecki) and Dean (Jensen Ackles) Winchester in the final season of Supernatural.

As viewers saw at the end of Season 14, God's (Rob Benedict) anger included bringing back several familiar monsters from the show's past. And now, in the Season 15 trailer below, the Winchesters are clued in on that fact thanks to a case exactly like the one from the pilot: a Woman in White.

We'd like to see Sam and Dean save people from these things (again) in Season 15.

Dean's not worried that it's just him and his brother against "every soul in hell." "I like those odds," he says. And Sam's looking ahead to what comes after: "If we win this, we're free." But will Sam and Dean both be alive when it's over? That's the question for the season.

Watch the trailer below for a look at the final season and take note of the callback at the end. Plus, click through the gallery above for a look at the Season 15 poster and premiere photos, which include Castiel (Misha Collins) taking on zombies.
