Michael lands at Tangier in Morocco after crossing the Straits of Gibraltar, and passes through the High Atlas mountains after brief stops in Fez and Marrakesh. From here, the Sahawari people help him to negotiate the harsh, rugged terrain and guide him south to the Mauritanian border.

After a brief stopover in cosmopolitan Senegal, Michael endures two nights aboard the train to Bamako, where he meets up with the renowned kora player Toumani Diabete. Meanwhile, the Dogon people of West Africa introduce Michael to some of their origin myths, and a trip down the River Niger turns out to be far from plain sailing.

Michael reaches Timbuktu along with a camel train carrying the giant salt blocks that made the city one of the greatest centres of Islamic learning up until the 16th century. He wanders through the rubble that is 21st century Timbuktu to find the Imam who shows him original astronomical textbooks that predate Galileo's discoveries by 200 years. Leaving one of Timbuktu's most famous addresses, the house of Alexander Laing, the Scottish explorer who had his thoat slit for not converting to Islam, Micahel heads East to the land of the Wodaabe. These nomadic herders are some of the last true pastoralists of the African continent - famous as much for their male beauty pageant as their stylish cattle. Living in the bush with them, Michael watches the complex rituals surrounding this extraordinary annual pagaent, the 'Gerewol', where the girls get to choose the prettiest boy. It is the season after the rains, a time of relative plenty for the nomads, and Michael's Wodaabe family, led by the English-speaking Doulla, travel to Ingall for the Cure Salee - a gathering of clans that takes place every year. Amidst the chaos of camel races, shopping and general mayhem, Michael meets up with a group of Tuareg for the next leg of his journey, a camel train across the Tenere desert to Algeria. Omar introduces him to the delights and vicissitudes of life on the move in the most desolate landscape on the planet. Walking 12 hours a day, eating the odd sheep and learning the rudiments of Tamashek, the language of the Tuareg, Michael finally gets to grips with the heart and soul of the desert. The going is tough, but the sense of comradeship with both the other cameleers and the camels, who are their lifeline, is palpable.

Michael arrives at the border of Niger and Algeria, the most desolate crossing, and then turning north Michael passes through the mountains of the Hoggar massif before pausing in the oil and gas fields of central Algeria. Then onto Libya to attend the very last reunion of the Desert Rats of Tobruk, before turning west along the North Coast past deserted classical sites at Apollonia, Cyrene and Leptis Magna. Crossing into Tunis, Michael re-lives the filming of The Life of Brian in Monastir, before taking the Maghreb Express to the dangerous city of Algiers, and then west to Algeria's second city, Oran. Just along the coast is Ceuta, a Spanish enclave on Morocco's coast, where Michael talks to would-be immigrants before returning to Gibraltar. En route he learns of the terrible fate that has engulfed many Saharan people who attempt the eight mile crossing.
