Did you Know?
-Police psychologists review recordings of a man(De Niro) who states his name as Det. David Fisk, the "Poetry Boy" killer. The Poetry Boy earned the moniker for his MO of murdering criminals and leaving short poems with thier bodies. Fisk reveals that he looks up to his partner of almost 30 years, Tom Cowan(Pacino) and considers him a role model of how a cop should be. Pacino's character is known by the nickname "Rooster" and De Niro's character is known as "Turk".
-These recordings provide a story and the film opens with victim #10, a drug dealer named Robert "Rambo" Brady(Rob Dyrdek). Turk and Rooster investigate the murder with the less experienced Det. Corelli(Carla Gugino), Perez(John Leguizamo) and Riley(Donnie Wahlberg). When they find a poem on the body, they link it to the Poetry Boy
-As Poetry Boy murders acquitted rapist Jonathan Van Luytens and Father Connell, a Catholic priest and child molester(kids including Poetry Boy himself), stress builds between Turk, Corelli and Perez. Turk is now living with Corelli, who happens to be Perez's ex-girlfriend. Poetry Boy assaults an attempted 14th victim, Russian mobster Yevgeny Mugalat, but when he is found to be alive, he attacks Perez and Corelli. Perez and Riley suspect Turk of being Poetry Boy due to his markmanship skills and psych evaluations, so they arrange a secretly supervised meeting between Turk and a drug dealer, Marcus "Spider" Smith(Curtis "50 Cent" Jackson). Turk proves his innocence during an encounter with the drug dealer as he has the "wrong" gun and humiliating but obviously wrong poem. After Perez and Riley leave the scene, Rooster kills Spider. During this, Rooster accidentally drops his diary
-Turk stumbles upon and reads Rooster's diary, where he claims Spider as victim #14. Rooster puts Turk in front of a video camera and forces him to read the journal. At this point, it's known and realized that the recordings from the film's beginning and the narration merely set up Turk as bait and Rooster is the Poetry Boy. Turk's name is actually Tom Cowan and Rooster's name David Fisk. It turns out that Rooster lost his faith in justice when Turk, an otherwise "righteous" cop, planted a gun at the house of acquitted child molester Charles Randall(Frank John Hughes), convicting him. This leads him to taking justice into his own hands.
-When Turk finishes, he chases Rooster to a construction site. Rooster fires to convince Turk to report that the Poetry Boy is assaulting a police officer, resisting arrest and fleeing, but Turk resists. When Rooster takes aim at Turk, Turk fires, striking Rooster in chest. When he calls for an ambulance, Rooster begs him to withdraw the ambulance. This allows Rooster to bleed to death.
