Amongst the crackpots and cranks and a bare handful of people looking for missing friends and relatives, they come across Jasper Willens, who identifies the angel as Lena Willens, his wife. Crews and Reese discover that their fallen angel was part of a scam targeting American men who marry Russian brides. They find themselves trying to track down the ringleader of the human trafficking organization that is running the scam, a Russian who appears to be untouchable.
