The rain begins in Australia. Kevin returns to the world of the undead where he is tasked with locating Evie Murphy, Christopher Sunday, and the children of Grace Playford. Despite successfully finding all of them, none of the parties are able to comprehend the messages that he delivers. In the alternate reality Kevin resumes his role as an international assassin (aided by the departed Dean), but soon realizes he has a second doppelganger as the President of the United States. He subsequently alternates consciousnesses between the two. As President, Kevin is manipulated by his Secretary of Defense Patti Levin to launch a nuclear attack that would devastate the world, despite resistance from his Vice President Meg Abbott. When both Kevins meet, they learn that the key to the nuclear launch is in the assassin's heart, which the President must cut out. Before they carry their task, the Kevins realize their regret in their handling of Nora and decide never to return to the undead world again. Patti and President Kevin watch the nuclear apocalypse as Kevin returns to the world of the living, where the rain has stopped.
