Raymond Avilla joins the LAPD's Internal Affairs Division (IAD) and is assigned to investigate the drug bust with partner Amy Wallace. They learn that Stretch abuses drugs, has a history of excessive force, uses racist language even under formal IAD questioning, and may be corrupt. Stretch is also revealed to be abusive to his wife Penny, whom he suspects of infidelity, and has a subservient friendship with Peck. Avilla eventually begins to look into Peck, who is held up as an LAPD role model but whose lifestyle (including spousal support for three ex-wives and eight children) is hard to justify with a patrolman's salary alone. After an altercation with Peck, Fletcher agrees to help Avilla's investigation. It is gradually revealed to the audience that Peck not only has a widespread web of corruption based on extortion, favors to cops and criminals alike and complicit dealings with pimps, but also moonlights as a hitman. This latter facet is revealed when businessman Steven Arrocas offers Peck $15000 to kill his own parents and is met with an angry haggle for a higher sum.
