Lev and his guide Boston trek from Rwanda's rainforest, through remote, lawless regions of Tanzania, into Uganda. They dodge crocodiles and hippos, go to a wedding and get a hero's welcome in Kampala.

Lev and Boston reach South Sudan. They spend time with the Mundari tribe - a highlight of their epic journey - and encounter the effects of the young nation's civil war.

Levison tackles the Sahara desert with friendly Sudanese guide Moez, charismatic nomads Awad and Ahmad and three badly behaved camels, experiencing spectacular sights that few outsiders have ever seen

After seven months of hiking, Levison Wood reaches his final country - Egypt - and with 900 miles still to go to reach the Mediterranean, the authorities give him just 45 days to finish. After walking the barren shores of Lake Nasser and exploring deserted temples, Lev reaches Aswan and spends a night at a historic hotel. Moving on, he discovers more of Egypt's wonders, from magnificent buildings in the ancient city of Luxor, to the Pyramids of Giza, where he's given a hero's reception. The journey then takes him through strongholds for the Muslim Brotherhood opposition group, and as the security situation deteriorates he finds himself accompanied by police vans and armed officers.
