Zoi Winchester is a Hunter who just wants to be a normal girl who has a normal life and normal parents. But that doesn't happen. When her cousin, John Winchester, and her Dad, Dean Winchester, show up on her doorstep and tell her that her Uncle Sam has gone missing, she doesn't know what to do. Zoi still holds a grudge against her father for leaving her with Sam when she was young, and doesn't want her lives crossing paths.
