Frank causes tensions in the stevedores union when he plans to run again for treasurer, despite an earlier agreement to let Ott take the position next. Ziggy and Johnny Fifty steal several cars from the docks, with plans to fence them to Glekas. When Ziggy tells Glekas the cars were put into containers, Glekas cuts Ziggy's share. The ensuing argument escalates to the point where Ziggy impulsively takes a gun and kills Glekas. Ziggy breaks down at the scene as the police arrive. He is questioned by Landsman and signs a confession. When Aimee questions Nick about the sums of cash she has found hidden in his room, he admits he is being paid off the books by The Greek. When they learn about Ziggy's shooting, Nick and Frank trade recriminations. Nick drowns his sorrows in a local park, where he is joined by Ziggy's ex, Prissy.

Valchek, annoyed that the detail has shifted focus away from Frank, calls in the FBI to take over the case. He hands them all the detail's information and requests their help in recovering his surveillance van. The Bureau agrees to share the case with Daniels and Pearlman on the condition that they focus attention on the union. Bunk accompanies McNulty on a fishing trip to disguise their surveillance. Meanwhile, Greggs and a now-pregnant Cheryl have an argument. Back at the detail, Greggs questions Beadie about balancing her police duties with being a mother. After the FBI agents offer to help trace the contraband containers' origins, Valchek arrives at the detail and lays into Daniels for failing to deliver a case on Frank. He insists Prez leave the detail, but Prez refuses to go and punches Valchek when he insults him. After an outraged Valchek leaves, Prez turns in his gun and submits himself to Daniels for a reprimand.
