A rash of abductions of young boys that end up brutally murdered is plaguing London, and police are powerless to stop it. When William Moriarty discovers a clue linking all the victims, he and his brothers take an interest in the case.

Albert invites the brothers to come live at the Moriarty's estate, but the pair are not warmly welcomed by the other members of the household. Albert grows increasingly disturbed by his family's intolerance, and resorts to drastic measures.
