Over the years, after dozens of bloody adventures, they have faced everything from the yellow-eyed demon that killed their mother to vampires, ghosts, shapeshifters, angels, and fallen gods. They even came face to face with Lucifer and the Four Horsemen in averting the Apocalypse.
With the help of allies — both human and supernatural — they’ve discovered that every threat they vanquish opens a new door for evil to enter in. In the show’s eighth season, their supernatural hunting expedition led them directly into an age-old power struggle involving the King of Hell, legions of warrior angels, and a series of divine trials to prove themselves worthy of sealing the Gates of Hell forever. With the help of their protector, the fallen angel Castiel (Misha Collins), Sam and Dean’s lifelong quest to rid the world of evil will take everything they’ve got. As dawn arrives after their endless struggle and sacrifice to defeat the world’s monsters, they know that, come nightfall, something otherworldly — something supernatural — will claw its way out of the shadows, demanding their attention.
