Undertow

Ziggy's (James Ransone) skills as a drug dealer come into question again as he screws up, bringing down the wrath of Cheese (rapper Method Man), who supplied him. Cheese takes Ziggy's prized Camaro, and threatens to kill him if he doesn't pay what he's owed, plus interest. Ziggy goes to Nick (Pablo Schreiber) for help. Nick asks Cheese for the car back so Ziggy can sell it and pay him, but Cheese has other plans. Freamon (Clarke Peters) finds out he's been added to Daniels' (Lance Reddick) detail, leaving Bunk (Wendell Pierce) to deal with the 14 murders. Daniels also adds Carver (Seth Gilliam) to the team, reasoning that Carver wouldn't dare betray him again. Carver and Greggs (Sonja Sohn) take photos as Herc (Dominick Lombardozzi) goes undercover to buy drugs from the white boys who sell to the dock workers. Bunk and Russell (Amy Ryan) go back to the docks with grand jury summonses, but Sobotka (Chris Bauer) angrily denies being involved in the girls' deaths, and lets them know that none of his guys will talk. Russell finds an informant, a stevedore who tells her where to look for evidence of the missing container -- the computers. McNulty (Dominic West) takes time out from trying to identify "his" dead girl to bring in Omar (Michael K. Williams), so he can prepare to testify in the Gant murder case. Sobotka tells Vondas (Paul Ben-Victor) that he doesn't want to do business with them anymore, but The Greek (Bill Raymond) won't take no for an answer. Stringer (Idris Elba) gets advice from a professor on how to turn his business around, and gives advice to Avon (Wood Harris) about how to deal with D'Angelo (Larry Gilliard, Jr.), Desperate for cash and with little legitimate work at the docks, Nick and Ziggy are drawn deeper into The Greek shady world.
