Sam and Dean are left to pick up the pieces after the loss of their mother, the demise of Crowley and the heartbreaking death of Castiel. The birth of Jack leaves the Winchester brothers with differing opinions on how to deal with a Nephilim. After being dragged into the breach, Mary must learn to survive Lucifer and an apocalyptic world.

When her friend is murdered by a wraith with a taste for psychics, Missouri enlists the help of Dean and Jody to protect her granddaughter, Patience, who has no idea she shares her grandmother’s trait and could be next on the wraith’s hit list. Meanwhile, Sam continues to work with Jack on learning how to control his powers.

Jack, desperate to prove to Sam and Dean that he is good and that he can control his powers, enlists the help of a dreamcatcher named Kaia to help him find Mary Winchester and save her from the alternate universe. However, when plans go awry, the Winchester brothers are the ones who need saving.

When Sam and Dean go missing, Jody Mills calls Claire Novak, the rebellious rogue hunter, and tells her it is time to come home – they need to find the Winchesters. Claire returns and reunites with Alex Jones, who has stayed behind with Jody and tries to balance a “normal” life with being a part time hunter. While Jody is happy to have Claire home again, she’s plagued by Patience’s disturbing vision involving her adopted daughter. Claire and Alex search for Kaia Nieves, the dreamcatcher responsible for opening the rift that Sam and Dean went through, as she holds the key to their whereabouts. Jody calls her friend, Donna Hanscum, to round out the team and the women head off on the most important hunt of their lives.
