Meet the Winchester boys: Dean, Sam and… Adam. The Winchesters discover they have a younger half-brother, whose mother vanishes just as a long-dormant grave robber renews his ghoulish career.

Sam, Dean and Castiel investigate a string of suspicious deaths that have a biblical element to them.

Hoping to find a weapon powerful enough to defeat Amara, Dean convinces “Castiel,” who is still Lucifer, to send him back in time to 1944 to the fated submarine mission…

With some help from Charlie, Sam and Dean inadvertently release two individuals contained inside of the Men of Letters bunker: an evil witch, and a young woman, both imprisoned since…

Sam and Dean tangle with the God of Time, who sends Dean back to 1944, where he is immediately arrested by none other than the one and only Eliot Ness….

Back to the future, Castiel sends Dean to 1973 Lawrence, Kansas, where he meets a nice young couple named John and Mary Winchester. Dean’s parents. And Mary has a secret.
