After their mother's death in a suspicious fire that burns down their house 22 years prior, Sam and Dean Winchester's father goes missing during a "hunting trip". As a result, Dean tracks down Sam at Stanford University and they begin to live a life on the road, in Dean's black 1967 Chevrolet Impala with Kansas license plates. However, their father is not a typical hunter: he hunts supernatural creatures like ghosts, vampires, and spirits, and has trained his sons to do the same. Along the way, Sam and Dean save innocent people, fight creatures and ghosts, and collect clues to their father's whereabouts.
