Chege was from Karagita, the largest of the slums that has sprung up beside the lake in the last twenty years. In that time, the population of Naivasha has rocketed from 30,000 to 350,000 as a desperate tide of impoverished migrant workers arrived in search of employment on Kenya's flourishing flower farms. This has created squalor, crime and, in the minds of Root and her fellow naturalists, ecological apocalypse.

This film tells the story of the extraordinary life and brutal death of Joan Root, and of her campaign to save the lake she loved. Who killed Joan Root? Was it the fish poachers, whom Root stopped from plying their illegal trade in a bid to save her beloved Lake Naivasha? Was it her loyal lieutenant Chege, whom Root ultimately cut off from her payroll? Or was it one of her white neighbours, with whom Root had feuded?

Through the telling of Root's story, the film opens a window onto contemporary Africa and the developed world's relationship to it. For it is the Kenyan rose, which is exported by the millions on a daily basis from Naivasha, that has brought not just jobs and foreign exchange earnings, but a population explosion that has caused the destruction of the environment Root worked so hard to stop. Her campaign may have ultimately cost her her life.
