By the time Norwegian explorer Helge Ingstad uncovered the remains of a Viking settlement at l'Anse aux Meadows on the northern tip of Newfoundland in 1960, he had had a lifetime of discoveries. While searching the more remote parts of the world for traces of Norse exploration, his travels took him from the Sierra Madre Mountains of Mexico to the northernmost regions of Canada. His numerous expeditions, many of them recorded on film and narrated by Ingstad, form the basis of this documentary about a man who is said to have discovered America in a way that few have or ever will.
