The earthquake that struck Haiti on 12 January caused death and destruction on a massive scale. Tens of thousands were killed instantly, thousands of others were buried under the rubble and a lucky few were dug out alive. Filmed over the six months after the disaster, This World follows four of the few who were rescued from a death beneath the rubble: a three-year-old child awaiting adoption; a musician; a student who became a Christian after being rescued, and teacher fighting to reopen his school; a single mother trying to keep her family safe; and a family whose daughter was rescued after nine days. Haiti, one of the poorest countries in the world, was ill-equipped to cope with a catastrophic earthquake. But as the months pass, the film shows that life for its survivors is hard, but not without the odd glimmer of hope. Sophie Okonedo narrates.
