The now human Castiel finds himself on a mission to locate the two young children of Judith Horvath, as they have been targeted by demons. So he travels to Brighton, England in an attempt to retrieve them, having been sent by another angel named Malachi. Judith's young daughter, Edith, seems to have an effect on Castiel. There's something about her that he can't quite shake. And when he makes a connection between Edith and an event that occurred in 2004, it makes everything even more complicated.
