Dean Winchester is a famous hunter in the hunting community and recognised by American Hunter's Association. He's asked to take in a kid , Sam Smith , to train him to be the next best hunter from the American Hunter's Boarding School. Dean is reluctant but agrees. He's a hardaas and he doesn't care about the kid. No matter what , Jo says.

Three years ago a big fight took place between John , Sam and Dean. The fight resulted in the breaking up of the Winchester family in two parts : John hunting together with Sam while Dean hunting alone. But now a demon from hell is after Dean and they would do everything they could to protect him. Even if Dean hated them and didn't want them around. Also he's got kids of his own.
