In Season 7, Sam and Dean fight demons. Real demons, like Lucifer, who tortures Sam with visions of Hell. Private demons, as the brothers face a traumatic personal loss when Bobby is cut down by alien forces. And 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?

After defeating the Leviathan, Sam and Dean set off on an epic quest to seal the Gates of Hell last season. Facing a series of trials, the Winchesters soon found themselves in the middle of an age-old power struggle between the King of Hell and legions of warrior angels. But with the angels cast out of heaven and walking the earth, things just got very unpredictable.

After a year apart, Sam and Dean are reunited in the Eighth Season premiere. After escaping from Purgatory with the help of a vampire named Benny, Dean heads straight for Sam, but the reunion isn't exactly everything he imagined it would be. Although Sam drops everything to join his brother, leaving the life he had grown accustomed to enjoy turns out to be harder than he imagined. In the meantime, Benny’s help turns out to be more than what Dean bargained for. 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. If only they could agree – is this a “family business” or isn’t it?
