Three years after the epic adventure described in Around the World in 80 Days, Michael Palin was off again. Not circumnavigating the globe, but journeying from one end to the other: the North Pole to the South Pole. Following the 30 degree east line of longitude and using aircraft only as a last resort, Palin and his team endured extremes of heat and cold as they crossed 17 countries on trains, trucks, ships, rafts, ski-doos, buses, barges, bicycles, and balloons.
