Da Vinci, Leary, and Sunny are in Seattle attending an international Homicide Conference. A presentation by San Francisco-based FBI Special Agent Charlotte Turner turns up similar cases across the Pacific Northwest, and appears to include the death Da Vinci is currently working to solve. Turner comes to Vancouver and Da Vinci finds himself coordinating an investigation that has international implications. As more abductions/murders fit the pattern it seems that a couple, Dean and his wife Mona, are responsible. Joanna, a young woman who was abducted but managed to escape, leads Shannon and Leary back to the farmhouse where she was held and they arrest Dean. Mona, however, has managed to sneak across the border into the States and Da Vinci offers Danny a deal if he can find out where she is. Meanwhile Da Vinci finds himself struggling with the ethics of paying Dean for information about other victims.
