Tonight's episode uncovers life in Olusosun rubbish dump. Here, around a thousand people live on top of the rubbish in houses built from scrap. It looks like the end of the world, but the film reveals that there is order – and honour – among this seemingly chaotic environment. There are shops, bars, restaurants, cinemas, even a mosque, and the scavengers have set up their own kind of government, with a democratically elected chairman at the head.
