AKA (2003)

Dean, a troubled, working-class lad from London, lands a job in a high-end art gallery and glimpses a world where the right name means instant acceptance. When the blue-blooded gallery owner takes him under her wing and into her family, the temptation for Dean to strip her son's aristocratic identity and join the jet-set life of parties, drugs, and status proves too powerful to resist. He falls victim to human ruthlessness and vulnerability.
