In the first episode of a three-part story arc, Bolander (Ned Beatty), Howard (Melissa Leo), and Felton (Daniel Baldwin) are ambushed and shot down when attempting to serve a warrant. In his efforts to track down the suspect, Pembleton (Andre Braugher) is partnered with a detective who prefers to use a bizarre psychological approach to crime-solving, and is also given a helping hand by Bolander's former partner Mitch (Tony Lo Bianco). Complicating matters is the realization that the shooting might have been averted had it not been for a disastrous clerical error. ~ Hal Erickson, Rovi
