All Hell Breaks Loose

"All Hell Breaks Loose" is the joint title for the two-part second-season finale of The CW television series Supernatural. It consists of the twenty-first and twenty-second episodes of the second season. "Part One" was first broadcast on May 10, 2007, and the second part aired the following week on May 17, 2007. The narrative follows series protagonist Sam Winchester (Jared Padalecki)—a young man who travels the continental United States with his brother Dean (Jensen Ackles) hunting supernatural creatures—as he is abducted by series villain Azazel (Fredric Lehne) and sent to an abandoned town. Azazel intends to find a leader for his demon army by having Sam and other psychic children like him fight to the death. Sam is eventually killed, but is resurrected after Dean sells his soul. The sole survivor, Jake Talley (Aldis Hodge), is sent by Azazel to a cemetery protected against demons, where he opens a gateway to Hell. At the end of the episode, Azazel is finally killed by Dean with the mystical Colt revolver, but not before hundreds of demons are released into the world.
