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. On the home front, Greggs is cold toward a now-pregnant Cheryl. 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.
