Comedian Lenny Henry, actress Samantha Womack, TV and radio star Reggie Yates and presenter and journalist Angela Rippon agree to swap their lives of privilege and luxury for a week living and working in Kibera- reportedly Africa's largest slum, and one of the most impoverished places on earth.Stripped of all of their possessions, the four volunteers move into mud shacks to live on their own for three days and nights. How does Lenny cope earning less than two pounds a day making and selling samosas on the streets of the slum? Will Sam return to work after witnessing desperate tragedy during her day cleaning in Kibera hospital? How will Angela react to being offered work as a sex worker, the only way to make money for many women in the slum? The highest paid job in Kibera is cleaning out the public pit latrine toilets - the question is, will Reggie agree to do it?
