For centuries explorers set out to make their names famous by discovering and mapping the ends of the earth. To be the first to set foot on new land meant a permanent place in the history books and fame throughout their lifetime. But the reality of exploring was dangerous and today's episode documents two failed polar expeditions; the quest for the Northwest Passage in 1845 by Sir John Franklin and the race to the South Pole with the 1910-1913 Terra Nova Expedition led by Captain Robert Falcon Scott. Both are harrowing tales that ended in tragedy that are not to be forgotten.
