A deadly assault leaves a postman dead and a woman named Kitty Lansing (Christina Haag) near death. The detectives manage to follow the trail of clues to a serial killer, who willingly confesses. But several surprises await the D.A.'s office in their prosecution -- and there is a heated confrontation in store for A.D.A.'s McCoy (Sam Waterston) and Carmichael (Angie Harmon). ~ Hal Erickson, Rovi
