An attorney found floating in a swimming pool appears to have suffered a heart attack. Before long, however, a man confesses to killing the attorney, giving up himself and an incriminating videotape to homicide detectives Pembleton (Andre Braugher) and Bayliss (Kyle Secor). Further complicating matters is the presence of the National Security Agency, who serve up a murder suspect of their own -- resulting in a major blowup by Bayliss. Meanwhile, Kellerman (Reed Diamond) is determined to find out who has been stealing lunches from the homicide unit. ~ Hal Erickson, Rovi
