Monsters roam the earth. While some might dismiss their existence as myths or urban legends, the Winchester brothers—Sam and Dean—are all too aware of the dangers lurking in the dark. Cruising in their 1967 Chevrolet Impala, these brothers have dedicated their lives to destroying any supernatural threat to human life. From shapeshifters to werewolves, vampires, ghosts, and even demons, the Winchesters hunt down and kill every evil entity they can find, all while searching for the creature responsible for their personal tragedy.
