The epic journey of the Winchester brothers come to a close as Supernatural enters its final season.
Sam (Jared Padalecki) and Dean (Jensen Ackles) and the angel Castiel (Misha Collins) have conquered monsters, demons, Heaven and Hell, and in the show's 14th season, the Winchesters grappled with the Archangel Michael possessing Dean.
In a valiant act, Sam and Dean's surrogate son Jack (Alexander Calvert) destroyed his soul to redeem his adoptive father.
But this proved to be a fatal error, leading to the accidental death of Mary Winchester.
The 14th season also featured the return of John Winchester (Jeffrey Dean Morgan) for the show's 300th episode.
Now, as their 15th and final season comes to a close, Sam and Dean find themselves facing a threat beyond anything they've ever grappled with ... anything they've ever imagined: God himself.
In the Season 15 premiere, "Back and to the Future": Picking up here we left off last season, Sam, Dean and Castiel are left to defend the world after all the souls in hell have been released and are back on Earth and free to kill again.
Supernatural is from Warner Bros. Television in association with Wonderland Sound and Vision, with executive producers Robert Singer, Andrew Dabb, Eugenie Ross-Leming, Brad Buckner and Bob Berens.
There are 20 episode in Season 20. The first 12 episodes aired on M-Net City before the season went on hiatus.
