Awakening in bed with hoodlum Jimmy Liery (Christopher Meloni), Diane Russell (Kim Delaney) can remember nothing that happened after Jimmy drugged her. Back at the 15th precinct, a victim of muscular dystrophy is murdered, and the victim's neighbors seem extremely nervous about providing information. As Bobby Simone (Jimmy Smits) and Andy Sipowicz (Dennis Franz) investigate a frustrating homicide involving a clever married couple, Lt. Fancy (James McDaniel) nervously anticipates informing Bobby and Andy that only one of them has been promoted to detective first grade. And back in Liery's apartment, a confrontation ends in gunfire -- and guess who pulled the trigger? ~ Hal Erickson, Rovi
