The thrilling and terrifying journey of the Winchester brothers continues as Supernatural enters its eighth season. Sam (Jared Padalecki) and Dean (Jensen Ackles) have spent their lives on the road, battling every kind of supernatural threat. Over the years, after dozens of bloody adventures, they have faced everything from the yellow-eyed demon that killed their mother to vampires, ghosts, shape shifters, 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 seventh season, their hunt for the dreaded Leviathans - monstrous creatures escaped from Purgatory - has cost them dearly.
Claiming the life of their best friend and father figure, Bobby Singer, and shattering their protector, the fallen angel Castiel, Sam and Dean's battle to somehow defeat the age-old Leviathan threat will take everything they've got. As dawn arrives after their endless struggle and sacrifice to defeat the world's evils, they know that, come nightfall, something otherworldly - something supernatural - will claw its way out of the shadows, demanding their attention.
