BLOOD DIAMOND- The film opens with a long paragraph of writing which explains the civil war in Sierra Leone in 1999, saying that thousands died and millions became refugees. while this is happening there is soft African music in the background (bongo drums). After the writing has disappeared  more slow soft music kicks in to set the scene of  the father and son back to their home made out of bamboo sticks and mud, everything is calm, there is then a steady shot of the beautiful African landscape behind the two of them . Then all of a sudden the music gets slightly louder and more violent, the father spots a large group of African rebels in jeeps with guns. The music increases even more when the father and son run away from them. The rebels head for the village, when they get there the rebels start shooting and attacking the villagers in cold blood. The music then stops all you can hear are the horrific screams of the villagers and the laughing of the rebels. After this the father gets taken by the rebels, the drums get louder and louder as his son runs away while crying.
