Supernatural

After a construction worker is killed by insects burrowing into his brain, Sam and Dean investigate a town's history and find that the new housing development is being built on sacred land.

Sam and Dean finally make contact with their father, but he tells them to stop looking for him and sends them on another ghost-hunting job.

Dean is contacted by his first love, Cassie, an African-American girl who asks him to come to Mississippi to investigate a string of racially motivated murders.

Sam and Dean head to Minnesota where a young boy witnesses a man vanishing into thin air.

After Sam has a vision of a family being attacked in the same manner as his mom was, the brothers and their father, John (recurring guest star Jeffrey Dean Morgan), head to Salvation, Iowa.

Twenty-two years ago, Sam and Dean Winchester lost their mother to a mysterious and demonic supernatural force. As a result, their father, John, raised the brothers to be soldiers. He taught them about the paranormal evil that lives in the dark corners and on the back roads of America...and he taught them how to kill it. Sam, however, wanted nothing to do with this violent and dangerous life, and he left it behind, until the day Dean appeared on his doorstep with troubling news. Their father had gone missing on a "hunting trip." Sam and Dean have spent the last year cruising the highways of the United States in their 1967 Chevy Impala, searching for their lost father and encountering creatures that most people believe exist only in folklore, superstition and nightmares. Along the way, they have battled the various supernatural threats--and each other as well, for their sibling rivalries and conflicts were never far from the surface. Finally, they found their father, just as he was closing in on the Demon who claimed their mother.
