Pilot
"Dean: Dad hasn't been home in a few days.

Sam: So he's working overtime on a Miller Time shift. He'll stumble back in sooner or later.

Dean: Dad's on a hunting trip. And he hasn't been home in a few days."

Twenty-two years ago, Mary Winchester was killed in the family home by an unknown supernatural creature, in front of her husband John and her sons, Dean and Sam. In the present day, Sam is a law student at Standford University with a girlfriend and a promising career -- until Dean arrives, asking for help in tracking down their father. John has been on one of his frequent "hunting" trips, where he tracks down and kills supernatural creatures: John and the boys have been doing this since their mother's death, but Sam left the hunting life after a falling out with his father. John hasn't returned from his latest trip, and Dean is worried.

Sam agrees to help Dean look for their father. They manage to come across the last creature he was hunting, a Woman in White, and destroy her. They also find John's journal, full of all his information on various creatures as well as the record of his hunt for the creature that killed Mary, but they can't find John. Sam returns to Stanford, but when he returns to his dorm, he finds his girlfriend suspended on the ceiling, bleeding and consumed by fire: the exact same way his mother died. Now that it's personal, Sam agrees to partner up with Dean and return to hunting, hoping that along the way they can find their father and finally destroy the creature that killed their mother.
