In the final part of the documentary, Lenny stays with 16-year-old Bernard and his four siblings. Theirs is a child-headed household that faces a daily struggle with poverty, where providing just one meal a day means back-breaking work for Bernard. Lenny finds the experience totally overwhelming, and when he discovers just how close the children are living to a latrine overflowing with raw sewage, he takes matters into his own hands... Meanwhile, Samantha Womack spends time with a woman trying to support her children by working in the sex trade; Reggie Yates meets two cousins desperate to build a life outside Kibera; and Angela Rippon learns about the harsh realities of HIV when she joins forces with a single mother.
