Sam and Dean Winchester have spent their lives on the road, battling every kind of supernatural threat. Over the years, after countless bloody adventures, they have faced everything from the yellow-eyed demon that killed their mother to vampires, ghosts, shapeshifters, angels and fallen gods. With the help of allies – both human and supernatural – they’ve discovered that every victory comes with a price.
In the series’ twelfth season, the Winchesters were reunited with their long-dead mother, Mary Winchester, and joined forces with the British arm of the Men of Letters. But things turned from bad to worse, with the return of Lucifer and the surprising revelation that the Devil is expecting a child. Now, Sam and Dean find themselves facing a creature of almost unimaginable power…one that could save the world… or destroy it.
