Sam (Jared Padalecki) and Dean (Jensen Ackles) travel to Sturbridge, Massachusetts, and discover a coven of witches that has killed two people. Ruby (Katie Cassidy) warns the brothers to stay away as the demon controlling these witches is very powerful and will surely kill them. Ignoring her plea, Sam and Dean go in after the coven and confront the head witch, who reveals Ruby’s past.
