Fifteen years ago, a teenage girl is assaulted and raped as she picks flowers. Cut to the present, and a man is killed in a hit and run. He has no identification, he is not reported missing nor wanted by the police. At the same time, a priest and his wife are found dead in an apparent suicide. Fredrika Bergman, along with Alex Recht's federal investigation unit, is assigned to the seemingly-unconnected cases. The investigations lead to a clandestine people-smuggling network that runs back to the 1980s, to a crime that went unreported, but whose consequences will reach further than anyone ever expected.
