When Sam and Dean Winchester were just kids, their mother was horribly murdered in front of their father by something “supernatural”. Their lives were never the same again. After their mother’s murder, their father took an interest in the supernatural and the unexplained and raised the boys as warriors with skills to fight back against the unknown and protect the innocent. 22 years later, with Sam and Dean grown up, their father suddenly disappears on a suppose routine supernatural hunt. Sam and Dean search for their father and along the way help anyone with a supernatural problem with the help from their dad’s journal that contains most of his knowledge about the supernatural that he had accumulated over his 22 years of none-stop obsessive hunting.
