Lawyer Sam Penny becomes Josh's surrogate father figure while he helps her search for the truth, and learns some she told nobody else about Grove and her, which is enormous, and convinces her to come clean to Kazin and her sister, who is far from the last to tell her part in the complex, sordid story of crimes and deceit...
