Set against the backdrop of the chaos and civil war that enveloped 1990s Sierra Leone, “Blood Diamond” is the story of Danny Archer (Leonardo DiCaprio), a South African mercenary, and Solomon Vandy (Djimon Hounsou), a Mende fisherman. Both men are African, but their histories and their circumstances are as different as any can be—until their fates become joined in a common quest to recover a rare pink diamond that can transform their lives.
