In 1977 Wangari Maathai planted seven trees in a Nairobi park, an act that grew into the Green Belt Movement and a direct confrontation with an authoritarian regime. This episode traces her journey from colonial Kenya to the Nobel Peace Prize.

We explore her Kennedy Airlift education, becoming the first woman in East and Central Africa to earn a PhD, the campaign that stopped a skyscraper in Uhuru Park, her arrests and beatings, and her historic 2004 Nobel Peace Prize.
