The thrilling and terrifying journey of the Winchester Brothers continues with the eighth season of Supernatural.
Twenty-seven years ago, Sam Winchester (Jared Padalecki) and Dean Winchester (Jensen Ackles) lost their mother to a mysterious and demonic supernatural force.
Subsequently, their father John (Jeffrey Dean Morgan) raised them to be soldiers. He taught them about the paranormal evil that lives in the dark corners and on the back roads of America... and he taught them how to kill it.
Sam and Dean have spent the last seven years battling the things that go bump in the night. Over the years, with the help of both fallen-angel, Castiel (Misha Collins), and the King of Hell, Crowley (Mark A. Sheppard), the Winchesters have straddled the line between good and evil.
Last season, the boys encountered their worst enemy yet, Leviathan, a highly adaptable, seemingly unkillable foe that takes the form of billionaire Dick Roman. Roman's plan is to turn the human race into a walking buffet for the Leviathan to feed on once the world has been taken over.
Roman discovers the existence of a tablet that is the only source on how to kill the Leviathan and stops at nothing to get it. The Winchesters, along with Castiel, also discover the tablet and the young prophet, Kevin Tran (Osric Chau), who is the only one who can decipher the text.
Using the tablet, the boys are able to beat the Leviathan, but after the blast, Dean and Castiel find themselves in Purgatory and Sam finds himself alone.
Season Eight begins with Dean's seemingly impossible escape from Purgatory, though Castiel is nowhere to be found. However, Dean isn't alone. He's returned with a mysterious comrade-in-arms whose reason for escape is perhaps more than Dean bargained for.
Meanwhile, Sam finds himself reconciling the life he discovered while Dean was gone with Dean's sudden reappearance. As the boys 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?
