In the episode (Supernatural Season 14, Episode 2), the story centers on the Winchesters' desperate search for Dean , whose body is currently being possessed by the Archangel Michael .
: Sam , Mary, and Bobby follow a lead to Duluth after hearing about piles of dead bodies with burnt-out eyes (Michael's handiwork). Along the way, Sam struggles with the leadership role of the remaining Apocalypse World hunters and his overwhelming fear for his brother's safety.
: Back at the bunker, Jack is struggling with the loss of his grace and his newfound mortality. Castiel tries to mentor him, but Jack feels useless without his powers. He visits his grandparents (Kelly Kline’s parents) in an attempt to find a sense of belonging, though he doesn't reveal his true identity to them.
: Michael, still inhabiting Dean’s body, is seen in Duluth, Minnesota. He is conducting brutal experiments on supernatural beings—specifically werewolves—trying to "improve" them. He aims to create a superior, more disciplined army of monsters that aren't hampered by basic human or animal instincts. He successfully "upgrades" a pack of werewolves so they are no longer vulnerable to silver.
: Sam , Mary, and Bobby find Michael's lab but are ambushed by his "enhanced" werewolves. After a difficult fight, the group is shocked when Michael suddenly leaves Dean’s body. Dean regains control, appearing confused and traumatized, claiming he has no idea why Michael just let him go.
