DiCaprio stars as Danny Archer, a mercenary smuggler searching for a priceless diamond amid the chaos of Sierra Leone's civil war; Hounsou (Gladiator), as a desperate father searching for his lost son; and Connelly (A Beautiful Mind), as a reporter searching for the truth behind the trade in 'conflict diamonds.' Forced to confront the brutal human cost of the diamond trade, Archer changes his search for financial reward to a quest for redemption.
