Romeo Is Bleeding

Jack Grimaldi (Oldman) leads more than a double life: He's a veteran cop, a two-timing husband and a corrupt mob informant. But when the Feds enlist him to protect Russian gangster Mona Demarkov (Olin) at the same time that the Mafia orders himto kill her, Jack's world of greed and lust begins to crack. Complicating this already dangerous situation is Mona herself, a seductive schemer who entangles Jack in a deadly, depraved plan of her own! (official distributor synopsis)
