Supernatural

Supernatural begins with brothers Sam and Dean Winchester, whose mother died mysteriously when they were young, traveling the country in search of their missing father, John, and fighting everything evil thing that crosses their paths along the way. When Sam and Dean find their father, new knowledge is brought to light about the thing that killed their mother, catapaulting the boys even further into the world of demons.

Season 2 follows Sam and Dean dealing and coping with the loss of their father and Sam's newfound psychic abilities. Along the way, they meet other children like Sam and uncover a sinister plan orchestrated by the demon that killed their mother twenty-three years earlier.

As a result of his demon deal to resurrect Sam, Dean has been given one year to live. Sam tries to find a way to save his brother from the deal with little success. Meanwhile, two new faces have arisen in the fight against Hell: Ruby, a seemingly helpful demon with a hidden agenda, and Lillith, Lucifer's right hand who wants Sam eliminated from the game.

After four months in Hell, Dean finds himself topside once again. The boys learn it wasn't a demon that pulled him from Hell, but an angel from Heaven named Castiel. Sam and Dean are pressed into the service of Heaven to stop Lillith from breaking the sixty-six seals and freeing Lucifer from his Cage, but Sam has a dark secret.

Lucifer has risen and the Apocalypse has begun. Castiel searches for the one person who could help them: God himself, but with the title fight between Michael and Lucifer looming ever closer, the Winchesters resist their roles as the archangels' vessels and try to fight not only the Word of God, but also their destinies.

On year after Sam took the swan dive into the Cage with Michael and Lucifer, Dean lives the normal life he never thought he would get, but it comes crashing down around him when Sam returns. The only problem? Sam is missing his soul. Meanwhile, it's Castiel versus Raphael for control of Heaven. Raphael wants to put the Apocalypse back on track, and Castiel is willing to do anything to stop him.

Castiel's stint as "God" doesn't last long, and he disappears into a lake of black goo, releasing the Leviathans, creatures from Purgatory, into the world. The Leviathans, led by Dick Roman, pose as humans and plan to fatten and sedate the real humans to eat them. As Dean tries to fix this new and dangerous problem, Sam endures delusions of Lucifer from his time in Hell, and the boys suffer an unimaginable loss.

Dean returns from Purgatory one year after the fall of Dick Roman to find that Sam has abandoned the hunting life in his absence. Also back from Purgatory, Castiel works with another angel named Metatron, the scribe of God, for the good of Heaven, but Metatron has ulterior motives. With the emergence of the prophet Kevin Tran and the mysterious tablets containing the Word of God, the Winchesters believe they have finally found a way to close Hell and rid the world of demons for good, but it comes at a price.

Castiel is human, Sam is in a coma, and a desperate Dean allows the angel Ezekiel to possess Sam and heal him from the inside by tricking Sam, but Ezekiel is not who he says he is. A new player joins the competition for the throne of Hell, and to stop her, Dean acquires the Mark of Cain from Cain himself, as well as the First Blade. But the Mark changes Dean into someone almost unrecognizable, and, when he is killed by Metatron, turns him into a demon.

Demon Dean is on the loose, but not for long. After he is cured, he continues to feel the affects of the Mark of Cain, and Sam and Castiel fear he will lose himself totally to it. While Sam and Castiel search for a way to remove the Mark, Dean learns from Death himself that removing the Mark will unleash the Darkness, an ancient and powerful being older than even God. Castiel works with a cunning witch named Rowena to find answers. In the end, Dean makes a tough decision with dangerous consequences, and the Darkness is released.

Free from the Mark at last, Dean has more problems than ever: the Darkness, revealed to be God's sister, is on Earth, taking the form of a young girl named Amara. As Amara grows, along with her power, the Winchesters pay a visit to an unfriendly face: Lucifer. Lucifer tricks Castiel into possession and uses Castiel's vessel as his own. With Lucifer free from the Cage and Amara still a threat, an unlikely ally returns from his long hiatus in the form of the prophet Chuck Shurley - God himself.

Resurrected by Amara as her parting gift to the Winchesters, Mary Winchester, the boys' mother, acclimates to life in the present. A new threat arises from across the pond. The British Men of Letters at first try to work with the American hunters, but soon take matters into their own hands and hunters become the hunted. In the middle of all of this, Lucifer has possessed the President of the United States and fathers a child, a Nephilim, with one of the President's aides. The Nephilim, more powerful than the archangel who sired it, could bring peace to the world, or could destroy it.

Still reeling from Cas's death and Mary's disappearance into the alternate world, Sam and Dean must face one of their biggest challenges yet: taking care of Jack, the toddler-teenager Nephilim son of Lucifer. Castiel returns from the Empty, the void where angels and demons go when they die, thanks to Jack, but the Winchesters' problems are far from over. Another challenger approaches, vying for Hell's throne. And in the alternate universe, where Sam and Dean were never born, the war between Heaven and Hell rages on, with Mary caught in the middle, but one archangel has his sights set on an even bigger prize.

Dean is possessed by Michael, Heaven is failing, and Jack is human. Dean hatches a desperate plan to keep Michael from taking over their world. When Jack dies, Castiel makes a deal with dire consqeunces to save him from the Empty. Jack solves the Michael problem, but as he uses his powers, his soul deteriorates, and he makes deadly mistakes that strain his relationship with the Winchesters. Deciding that Jack must be stopped, God (Chuck) steps in, but he quickly turns on our heroes when they refuse to play his games.
