Two brothers, Sam (Jared Padalecki, "Gilmore Girls") and Dean Winchester (Jensen Ackles, "Smallville"), witness their mother's paranormal death as children and grow up trained to fight by a distraught father who wants nothing more than to hunt down the thing that killed his wife. Sam escapes to college to start a new, normal life, but gets pulled back in after Dean shows up on his doorstep to tell him their father is missing. Following clues from their father's eerie phone message, the boys travel to a small town and encounter a violent and vengeful spirit called the "Woman in White."
