The season deepens the mythology by revealing that Azazel has been visiting special children—infants whose mothers he killed—and giving them psychic powers. Sam is one of these children, and his abilities (premonitions, telekinesis) grow stronger. The story introduces other "special children," including a powerful psychic named Ava, and sets up a final showdown at a ghost town where Azazel forces the remaining children to fight to the death. The finale, "All Hell Breaks Loose," is a turning point: Azazel kills Sam, leading Dean to sell his own soul to bring Sam back. Sam then uses his powers to kill Azazel, but the victory comes at a terrible cost. As a parting gift, Azazel opens a massive gate to Hell, unleashing hundreds of demons upon the world.
The series kicks off with a simple, driving premise: Sam and Dean's father, John Winchester, has gone missing on a hunting trip. Sam, attempting to live a normal life at Stanford University, is pulled back into the family business after his girlfriend, Jessica, is murdered by the same yellow-eyed demon that killed his mother 22 years prior.
