As the fourth-season finale of The Shield begins, everyone at The Barn is angry that Antwon (Anthony Anderson) got a deal from the DEA and is not going to be charged for the murder of two cops. Monica (Glenn Close) suggests to Vic (Michael Chiklis) and Shane (Walton Goggins) that they find a way to undermine the deal. Vic learns that Aceveda (Benito Martinez) visited both Juan Lozano and Antwon in prison, shortly before Juan was murdered. Suspecting that Aceveda might have had something to do with Juan's death, Vic confronts him, suggesting he find a connection between Juan and Antwon, because if Antwon murdered Juan after cutting the deal with the DEA, he could lose his immunity. Monica learns that Antwon is giving the DEA information about Bonilla (Al Cruz), a Salvadoran drug kingpin, so the team decides to try to bust him first, targeting gang leader Gusano (Pete Vasquez) to get information about him. Dutch (Jay Karnes) and Claudette (CCH Pounder) investigate a murder at a quinceañera. When the trail leads them back to the Walker foster home, an irate Monica makes several crucial decisions about the case that could jeopardize her captaincy.
