I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Paid in Full Movie plot: Ace (Wood Harris) is a young man from Harlem stuck in a dead end job at a dry cleaning shop. His sister's boyfriend, Calvin (Kevin Carroll), is a local cocaine dealer who tries to lure Ace into the drug trade with promises of fast money and women. Ace resists Calvin's temptations, not caring for his unsophisticated ways. Likewise, Ace's close friend Mitch (Mekhi Phifer) is a flashy, popular drug dealer who exposes Ace to drug dealing lifestyle. When Calvin gets arrested on drug charges, Ace ends up filling his position on the street. This happens after Ace starts getting cocaine from Lulu, one of the customers at the dry cleaners shop. Lulu has a top-quality supply of cocaine which Ace sells on the street at a cheap price, quickly luring away customers from other drug dealers. Ace operates on the mantra that there is plenty of money to go around and that everyone can "live and maintain." While Ace is building up his drug operation, Mitch is arrested for killing a stickup man who robbed one of his workers. When a fight breaks out between Mitch and another inmate, Mitch is aided by East Harlem inmate Rico (Cam'ron) who impresses Mitch by his ferocity and show of solitude. Mitch is able to beat his murder charge and both him and Rico join Ace's drug empire. The trio become extremely wealthy, buying foreign cars, jewellery and expensive champagne. Ace continues to more or less stay behind the scenes, while Mitch returns to his flamboyant lifestyle as a popular hustler. Rico is a ruthless enforcer who worries Ace with his overzealous behavior and high-profile lifestyle. When Calvin is released from prison, he tries to regain his position of power on the streets. Ace gives him a job overseeing his old drug spot, but Calvin feels dissatisfied with his menial position. When Ace refuses to let Calvin run his old block, Calvin attempts to rob Ace. Calvin grows increasingly anxious and kills two of Ace's relatives while Ace survives his shooting despite being shot in the head. Feeling physically and physiologically... My question: Where does Rico refuse to inform on anyone from?
