Over two hundred years ago in Africa, a woman tosses her young son to safety as she is hauled off by slavers. After a brutal sea passage, her second child is snatched away. Although the woman doesn't know it yet, her spirit is destined to roam the earth in search of her lost children. It will make its way to 1980s Brixton, where she watches teenage Michael attempt to stay out of trouble as riots spit and boil onthe streets; and to a poor village in Nigeria, where Ngozi struggles to better her life..
