In this episode Martin travels to the Tiwi Islands, swims with a whale shark, and visits the Houtman Abrolhos, a string of over 100 little islands. Martin Clunes also samples life on Rottnest Island, which has long been a playground retreat for mainland visitors.
Ade Adepitan embarks on the first leg of his epic journey around Africa. Starting in west Africa, this episode sees Ade traveling from Cape Verde to Senegal and the Ivory Coast, before finishing in Nigeria - the country of his birth. In Cape Verde - a group of tiny volcanic islands in the Atlantic - Ade visits a community living in the shadow of an active volcano. He also witnesses how solar power is transforming lives by bringing electricity to isolated communities. Ade's next stop is Senegal. Here he visits Goree Island - a former staging post in the transatlantic slave trade. He then travels down the coast to a fishing village, where he hears that much of Senegal's catch is being taken by foreign companies and turned into fishmeal to feed western livestock. Making a last stop on his journey through Senegal, Ade visits Lake Retba where he joins the workers who wade through the lake gathering salt which they sell for less than half a penny a kilogram. Ade's host has tried to escape poverty by migrating to Europe, but - like so many others - he never got further than the horrors of the camps in Libya. In the Ivory Coast, Ade meets more people who share the dream of getting to Europe. This time, however, they are footballers training to become professionals in Europe's big leagues. But it does not always work out, as many are scammed into giving their cash to dodgy football agents. The final stop is Nigeria, the country Ade was born in. In Lagos he meets some old friends who play para soccer, and he also visits the largest church building on the planet. Traveling out of Lagos, he discovers a country in chaos. Under armed escort, he hears about a conflict that has created hundreds of thousands refugees, but barely been reported on in the west. He finishes his journey at Nigeria's equivalent to Silicon Valley – a company that believes tech can transform the continent.
Michael begins the third leg of his journey in the mineral-rich state of Minas Gerais, where he learns about the Brazilian mining industry and meets some of the people dedicated to overturning the environmental damage it causes. He then heads to Rio de Janeiro, focus of the next World Cup and Olympics, where the authorities are ridding the streets of violent drug gangs that have controlled the city's shanty towns. On a lighter note, the globe-trotting broadcaster also learns to celebrate a goal like a well-known radio commentator and visits a `love hotel'.
