Chuck and Amara are gone, and the world has been saved, but that doesn’t mean all is perfect. Dean and Mary embark on a journey back to the Bunker and to find Sam and Cas, while trying to reconnect with each other after Mary’s resurrection. Meanwhile, Cas enlists help in his quest to save Sam and make good his promise to Dean, and Sam faces the “justice” system of the Men of Letters. And maybe, when it’s all over, and they all find each other again, they can try for something more, something new, in this life.
But nothing in life is free.
