Kevin Conway guest stars as police lieutenant John Flynn who, while on a stakeout with Briscoe (Jerry Orbach) and Curtis (Benjamin Bratt), kills a suspected drug dealer. The subsequent Internal Affairs investigation results in friction at the NYPD when Curtis refuses to testify that the dead man was going for his gun. This leads to an evidence-tampering charge against Briscoe and a battle between the D.A.'s office and a politically ambitious judge (Josef Sommer). ~ Hal Erickson, Rovi
