Client Sophie Keene revives the case when an unsigned painting turns up that depicts her sister in unmistakable detail. In need of help, Gen turns to one-time romantic interest SFPD Detective Mackenzie Hackett and his insider access to the cold case file. As Gen unravels the mystery the threads of her complicated romantic life fray out of control, and she is forced to confront her feelings about Mack and their unresolved past.
