A new crime series set in San Francisco launches with a late night phone call. The body of a young woman lies in a trash-strewn room of a derelict building in China Basin. With that, veteran San Francisco homicide inspector, Ben Raveneau, and his hard-charging new partner, Elizabeth la Rosa, catch their first case together. But they can't identify the victim and they don't know why she was there. A false confession misleads and the apparent suicide but possible murder of an SF homicide inspector on medical leave may tie in. When Raveneau and la Rosa finally catch a break they are led into the past and a long ago case. A woman famous for her charitable works moves into focus and the inspectors adjust yet again. Now they're close but are racing against someone intent on stopping them.
