Rita Rizzoli is a narcotics cop with a plethora of disguises. When a drug shipment is hijacked, the thieves don't know that the drug is unusually pure and packs of 'Fatal Beauty' begin turning up next to too many dead bodies. Mike works for the original owner of the drugs and tries to tell himself that since he does not handle the drugs, he is 'clean'. Mike becomes Rita's constant companion.
