Season 10 begins with Sam’s frantic search for his missing brother, who is gone without a trace. Meanwhile, with his grace failing and rogue angels still on the loose, Castiel will face the ticking clock of his own mortality as all-new threats emerge to once again push all of our heroes to their limits.

Following the release of the Darkness, this season follows the Winchesters and their allies as they find themselves fighting the most powerful supernatural entity they've ever faced.

As the Apocalypse grows closer, threatening to turn Earth into a battlefield soaked with human blood, Sam, Dean and Castiel struggle against daunting odds.

Now a different man, Dean vows to stop hunting and devote himself to building a family with Lisa and her son Ben. Then, mysteriously, Sam reappears, drawing Dean back into the old life. But Sam's a different man too. He's returned without his soul...

As Sam and Dean travel the back roads of America, hunting monsters who wreak havoc on the innocent, a new and more terrible foe hunts them: Leviathans, freed from Purgatory and immune to the brothers' arsenal of weapons and cunning. With Bobby gone, all Sam and Dean can rely on is each other. But will that be enough?

As the brothers struggle with their unexpected reunion, they make a shocking discovery that could lead them on a deeply personal mission to settle old scores

After defeating the Leviathan, Sam and Dean set off on an epic quest to seal the Gates of Hell last season. But with the angels cast out of heaven and walking the earth, things just got very unpredictable.
