There is a hostage situation at a casino/hotel. We then go into flashback and see what led to it. A woman has been killed in her home, shot in the mouth. Now everything points to her husband, who has a story that defies reality. Is he telling the truth or is he just a slimy nobody. Brass gets to show off his acting skills here as a hostage negotiator and the CSI's have to wade through a family situation. A sidebar. Warrick has an encounter with his own wife, straining their relationship.
