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.
It all comes down to this. In the epic season thirteen finale, Sam and Dean Winchester continue to be tested in the battle between good and evil, but one impulsive decision could alter the lives of one of the brothers forever.
