When two trash-picking boys from Rio’s slums find a wallet in amongst the daily detritus of their local dump, little do they imagine that their lives are about to change forever. But when the local police show up, offering a handsome reward for the wallet’s return, the boys, Rafael (RICKSON TEVEZ) and Gardo (LUIS EDUARDO), realise that what they’ve found must be important. Teaming up with their friend Rato (GABRIEL WEINSTEIN), the trio begins an extraordinary adventure as they try to hang onto the wallet, evade the police, and uncover the secrets it contains.
The Departed is set in South Boston, where the state police force is waging war on Irish-American organized crime. Young undercover cop Billy Costigan (Leonardo DiCaprio) is assigned to infiltrate the mob syndicate run by gangland chief Frank Costello (Jack Nicholson). While Billy quickly gains Costello's confidence, Colin Sullivan (Matt Damon), a hardened young criminal who has infiltrated the police department as an informer for the syndicate, is rising to a position of power in the Special Investigation Unit.
