Joanna Lumley’s spice journey continues on the African island of Madagascar. Travelling overland on the country’s notorious pot-holed roads, she discovers the secrets of the world’s second most expensive spice, vanilla. From the unique way it’s grown to how it’s dealt on the streets. She searches for gold with a poor gold-mining community and finds out how cacao is used to make some of the world’s best chocolate. The trip ends on the tourist island of Nosy Be, where the men participate in a dangerous martial art called Morengy and the women are paving the way for female equality.
