Holder falls from grace while Sarah tracks down Rosie's backpack. Richmond confronts the truth about his situation and Stan gets in deeper with the mob while Mitch resurfaces.
Holder is feeling the sting of having been betrayed by Sloane and the fact that Sarah thinks he’s a dirty cop. He makes a half-hearted effort to attend an Narcotics Anonymous meeting, but ends up leaving and falling back on old habits. However, unbeknownst to him, Sarah is beginning to question Holder’s involvement in the cover-up when she finds out about Rosie’s backpack - and attempts to get in touch with him. In the meantime, she continues searching for other suspects, concentrating on the Indian Casino and Beau Soleil, only to run up against a brick wall. But some recovered video footage may provide a much needed break in the case.
