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.
At the centre of this great sea, and surrounded by crystal clear waters, is Simon's first stop, the beautiful island of Malta. Driven by a surge of tourists, modern-day Malta is booming. But beneath the picture-postcard image lies a country accused of being a haven for money laundering and organised crime, where journalists can be murdered by car bombs. When Simon takes a ferry to his next destination, Calabria in southern Italy, he discovers a region in the grip of Europe's most powerful mafia, the 'Ndrangheta. With rare access to police and customs investigators, Simon follows an armed convoy carrying a ton of seized cocaine, joins a stakeout of a high-level suspect, and crawls through a huge underground warren of tunnels and bunkers built by fugitive mafia bosses. Travelling east along the southern tip of mainland Italy, Simon visits a turtle conservation centre, meeting Raoul, a loggerhead turtle rescued after swallowing huge quantities of plastic, a massive and increasing threat to Mediterranean wildlife. Simon helps release him back into the sea. Taking the overnight ferry from the heel of Italy, Simon arrives in one of the least-known but most beautiful corners of the Mediterranean, Albania. Under communist rule, Albania was isolated and shut off from most of the world. In a country now hoping for EU membership, Simon discovers an ancient culture of vendetta, where if an adult commits a crime, a child can be killed in revenge. Simon ends the first leg of his journey at a spectacular wildlife reserve where bird life is now recovering following the country's groundbreaking ban on hunting.
Simon travels travels down the east coast to the magnificent cities of Sydney and Melbourne in the final part of his journey. Simon's journey starts in Surfers Paradise near the city of Gold Coast, the Las Vegas of Australia. Behind the sun and surf, this area has become the organised crime capital of Australia. Police are cracking down on outlaw motorcycle clubs, accused of being criminal gangs. Simon meets the most notorious and feared biker group in Australia to hear their side of the story. Arriving in Sydney, Simon discovers a city of huge cultural diversity closely linked to its booming Asian neighbours, India and China. One in ten Aussies are now of Asian origin. Simon gauges Australia's attitude to immigration and meets the country's first Muslim ladies Aussie Rules Football team. On the very last stretch of the journey, Simon takes to the air to witness the devastating and deadly bush fires ripping through the country, before reaching his final destination, Melbourne, just in time to celebrate Australia Day.
Taking a ferry across the Strait of Gibraltar, Simon's first stop is Ceuta, a Spanish exclave surrounded by Morocco. This is one of the few land borders between Africa and the European Union. Simon joins the Spanish border police who check engines and even dashboards for stowaways trying to reach Europe. Migrant and refugees attempting to cross Ceuta's fortress border have quadrupled in the last year. Undaunted by Morocco's failure to issue a filming permit, Simon crosses the border as a tourist, tracking down a group of young migrants hiding out in a forest close to Ceuta. They have travelled thousands of miles, crossing the Sahara to get this far, and now they are just a 20-foot, razor wire fence away from their European dream. Crossing the Med to Spain, one the busiest shipping lanes in the world, Simon discovers huge numbers of dolphins and even giant whales surviving by dodging the ferries, container ships and oil tankers. Travelling along the arid southern Spanish coast, Simon takes to air to witness the sea of plastic that form over a hundred square miles of greenhouses. It is where much of our supermarket fruit and veg are grown, but as Simon discovers it is a massive industry built on the back of a low paid, migrant workforce. Following in the footsteps of four million Brits who make the journey every year, Simon travels to the Costa Blanca and its most famous resort, Benidorm. Derided by many, Simon is surprised to learn that high-rise Benidorm is now being hailed by experts as a model of sustainable tourism. The Mediterranean region attracts a third of world tourism and visitor numbers are predicted to rise to half a billion a year by the end of the next decade. Simon travels to a western corner of Corsica, a nature reserve that must be one of the most heavily protected bits of sea on earth, and one of the few places where tourists are actively discouraged from visiting. Lying on the beach, hiking in the mountains and watersport activities are all banned. The park's manager shows Simon the results, taking him for a dive in the fishiest place in the Med. In a sea where over ninety percent of fish stocks are over exploited, it is a beacon of hope in what is otherwise an uncertain future for the Mediterranean.
On board a timeless dahabiya cruise boat, the historian sets off on a 900-mile adventure up the Nile to Egypt's southern border, seeing the country as the ancient Egyptians once did. She arrives at Egypt's gateway to the world - the Nile's mouth - then meets the crew that will guide her upstream. A visit to the Cairo Museum and its collection of Egyptian mummies follows, before Bettany braves the underground tunnels of a collapsed pyramid.
