Carisi asks the SVU for help with a murder investigation when one of the witnesses shows signs of abuse.

Police patrolling Momma Sue's restaurant stumble upon an attack in progress. A woman is being assaulted and there is threatening graffiti on the walls. The victim is Jennifer Fulton (Josie Bissett), owner of the restaurant. After going to the hospital to get checked, she's in a rush to leave. Her husband, Craig (Ricky Aiello) is concerned, which leaves Benson (Mariska Hargitay) and Stabler (Christopher Meloni) to believe the suspect was not her husband, but could have been an underage drinker she busted earlier. The young man is Leon Ardilles (Victor Rasuk) and it turns out he was in the restaurant that night, and the paint on his fingernails matches the paint from the walls. He admits he was there and tagged the place, but Jennifer was already injured.

Bunk and Freamon chase their crime scene, a container ship, to Philly, where none of the crew finds it useful to speak English. Lt. Cedric Daniels--disgusted with his exile to the evidence control unit--lets it be known he's going to leave the department. On orders from Barksdale, Bell finds a way to set up the correctional officer, Tilghman, who's been harassing Wee-Bey. McNulty pursues the identity of the Jane Doe found floating in the harbor. A pair of young longshoremen--Frank Sobotka's son Ziggy and his nephew Nick--heist a container of digital cameras and sell them to men working for The Greek. After an ominous visit from his uncle, Avon Barksdale, D'Angelo agrees to stop getting high in prison, a wise move in more ways than one.

In the Season Three premiere, a wave of urban reform brings down the notorious Franklin Terrace public housing towers, forcing the Barksdale drug crew to find a new home on the streets of West Baltimore. Stringer Bell sets up shop using a new sales strategy for Bodie, Poot, Puddin and the rest of the gang, as he awaits the return of Avon from prison. McNulty, Greggs and the Detail look to make a case against Stringer with a wiretap on a drug ring run by his ally, Proposition Joe. Assigned to the Western District drug unit, Carver and Herc notch up the pressure on street dealers. Burrell is caught in a power play by First District Councilman Tommy Carcetti, an ambitious young man with roots deep in the ethnic politics of Baltimore. Mayor Clarence Royce, facing re-election next year, puts Burrell on notice that crime stats, and murders in particular, must come down, whatever it takes. The order from on high has put police commanders in the hot seat during the new Comstat meetings, where they are held up to aggressive criticism by Rawls and others before their peers. Daniels, too, is confronted by the reach of City Hall, as his promotion to major appears to be derailed because of his estranged wife's political ambitions. A rash of murders cuts short Bunk's day at the ballpark, as Bubbles and Johnny lose big in their latest caper for cash. On the eve of his parole, Cutty Wise is offered a new start on the outside by Avon, but after being released, he finds the drug life has changed.
