The Winchester brothers never had a regular life. Back when they were little kids, the boys had to rely on themselves and confront the harsh, unforgiving world all on their own. Now that they're all-grown-up, the fellas are fighting the biggest otherworldly threat humanity has ever seen. Plus, both Dean and Sam are trying to make sense of their past and face the demons from the early days. The angels and the demons are finally free, and they found a new home on Earth. The brothers have only one task: to put down the evil entities and protect the world from the scum from hell. It's all the courageous warriors know how to do and use their fancy car to drive around in America and chase after the monsters.
