Supernatural takes viewers on a journey into the dark world of the unexplained. More than 20 years ago, Sam and Dean lost their mother to a demonic force. Now, searching for the demon who destroyed their family, they encounter creatures that most believe exist only in folklore or superstition -- vampires, spirits, and even bloody clowns.
In the shocking ninth season finale, Dean feels the effects of the First Blade, and Metatron makes his move against humanity. Meanwhile, Sam Dean and Castiel face shocking consequences when taking the fight to Metatron.
