1: Africa
Simon Reeve's journey along the equator begins in Gabon, where he meets villagers who have been banned from hunting. They now perform traditional dances for tourists to earn a living. When it is time to continue, the team's drivers suddenly demand £1,000 per day to continue working. When the BBC crew refuse to pay, the whole team is abandoned in the rainforest. But Simon develops a temperature of 40C and starts vomiting blood. He is diagnosed with malaria and forced to rest before continuing along the path east toward Congo, Congo DR, Uganda, Kenya and Somalia.

2: Asia
Simon Reeve's journey along the equator across Asia begins off the coast of Sumatra, in the far west of Indonesia. A boat trip along the equator takes Simon to mainland Sumatra, where he hears fears about bird-flu and meets the Minang people, where men live as guests in their wives' family homes, and it is the women who propose marriage. On the second leg of his journery, Simon also travels through Kalimantan, Sulawesi and beautiful the Togean Islands.

3: Latin America
The third and final programme in the series starts in the Galapagos Islands, where Simon goes swimming with sea-lions. He then heads east towards Equador and then Columbia where he must negotiate the lawless border area before heading on to Brazil, and a chance to ride a mini tsunami wave on the Amazon tributaries.
