Whatever you do, you will always end up... here.
In May of 2007, Sam Winchester wakes up in his own grave, but digging himself out is the least of his worries. He's plagued by the psychic visions which have returned with renewed intensity and which all but threaten to cripple him. He reunites with Dean, only to find that the Yellow-Eyed Demon is still at large, about to put his world-ending plans into motion. A mysterious figure who know much more than he ought dogs Sam's footsteps, hinting at darker things to come. Soon Sam and Dean find themselves on a path that feels frighteningly familiar: toward Lilith, Lucifer, and the Apocalypse. Unable to shake the certainty that he's seen all of this before, Sam knows that this is his one chance to set things right, or die trying.
