Detectives Briscoe and Curtis investigate the murder of a prostitute, Gwen George, who was found shot to death in an alleyway. More interestingly, she had $2000 in cash on her and she has a record for having blackmailed one of her clients. There are several possible suspects, including a local store owner who's had it with hookers on the street in front of his store but CCTV footage clears him. They do catch one of the dead woman's clients, Dr. Mark Danforth, in a lie and they suspect she may have been blackmailing him. McCoy thinks they don't have a case but when Claire Kincaid thinks they do, he tells her to go ahead and prosecute the case herself. She gets the conviction but quickly begins to believe they have been manipulated by the real killer.
