Leah Glaser is found beaten to death in her apartment. It looks as if someone forced their way in, and then attacked her, but Briscoe and Green can't tell what's missing. They try to figure out who would have access to her apartment and find an ambulance driver who, they suspect, had a senior citizen robbery ring with his co-workers. But both drivers had alibis for the time of the murder. The driver dropped Leah off at the Federal Building and it's revealed she was a witness in the deportation trial of Stefan Anders, a Nazi. Leah was a slave laborer at Bobrek, a satellite camp of Auschwitz, which manufactured airplane and submarine parts and was in the process of giving her version of events as part of the Shoah project. She also picked him out of a lineup and Anders' visa photo matched his SS photo. Also, they see he has Leah's prized possession, a locket, which he claims he didn't take from her, but that someone sent it to him anonymously.

A young man is found stabbed to death outside a pizza parlor, with no identification. Detectives Briscoe (Jerry Orbach) and Green (Jesse L. Martin) soon learn, however, that he is Andrew Hatcher, an NYU student. Hatcher's grieving parents claim they got a call from him on his cell phone hours after the estimated time of death, but it turns out someone else made the call. Tracing the cell phone, they find a drug dealer named Jimmy Gaines (Gregory Russell Cook), who has Andrew's watch too. But he insists that he found Andrew's possessions in a dumpster. The police then find a blue denim shirt with blood on it nearby, but there is no trace of Jimmy's DNA or prints on it, so he is in the clear. They did find bovine blood on the shirt though, and the M.E reports that Andrew was stabbed with a six inch butcher's knife. They deduce that the killer worked in the nearby meat packing district.

Goren and Eames search abandoned subway tunnels for the killer of homeless men, whose bodies were sold to medical labs, then they learn that each victim had been issued a credit card just before his death.
