'What they need is a union.' -- Russell

Bunk and Freamon chase their crime scene, a container ship, to Philly. Lt. Cedric Daniels--disgusted with his exile to the evidence control unit--makes it known that he's leaving. On orders from Barksdale, Bell finds a way to set up the correctional officer who's been harassing Wee-Bey. McNulty pursues the identity of the Jane Doe found floating in the harbor.

'If I hear the music, I'm gonna dance.' -- Greggs

Sobotka reprimands his nephew Nick for stealing the cameras and orders him to bring the cargo back--too late. McNulty is on a self-assigned moral mission to identify his floater, but his old partner, Bunk, says they have a more pressing matter at hand: to find Omar so he can testify against a Barksdale trigger man in one of last year's murders.

'They used to make steel there, no?' -- Spiros Vondas

Ziggy loses his prized Camaro to drug dealers. Unable to dump the homicide investigation on other agencies, Rawls measures Bunk for the blame, if the cases go unsolved. Homicide detectives hand out grand jury summonses to stevedores involved in the homicide case, and port cop Beadie Russell talks to an old boyfriend to find out how cargo disappears from the docks.

'Don't worry, kid. You're still on the clock.' -- Horseface

Russell tells Sobotka the investigation is over, but, in fact, a port computer is cloned, and when a container goes missing, the detectives follow. Simultaneously, Greggs and Prez tap into a circuit of Russian prostitutes. With two sets of evidence, the detail goes to Pearlman. Neither crime merits wiretap--but a drug connect could give the case legs.

'It pays to go with the union card every time.' -- Ziggy

The Detail uses satellite technology to its advantage. Bodie is unhappy that Proposition Joe's people are slinging on his turf, but business flows--until a new face arrives. Stringer Bell looks to an unlikely solution to the problem. Valcheck visits the FBI in an attempt to get real results on the docks. Ziggy's deal with Double-G goes bad in a big way.

'Business. Always business.' -- The Greek

The Detail has a setback, while Russell and Bunk revisit Philly to look for evidence. Brother Mouzone talks with Stringer Bell about their agreement, leaving Bell to contend with a dissatisfied Avon Barksdale. Bubbles and Johnny pull another caper and McNulty and Greggs return to the Westside, where they discover new connections.
