Captain Robert Falcon Scott is an explorer. Finding rivalry not only abroad but amongst his peers at home, he is secretly overjoyed when Shackleton's expedition to the South Pole fails spectacularly.

Preparing for an expedition to the North Pole in defiance of government opposition, Amundsen confides to his brother his secret plans to take the South Pole.

Scott discovers that Amundsen is also heading for the Pole and the race is on. Friction amongst the crew is growing and the horses are found to be unsuitable…but more bad news is yet to come.

The rivalry between the two expeditionary teams increases, and they both discover just how harsh and unforgiving Antarctica can be.

When the spell of bad weather breaks, Amundsen's team manages to surge ahead, though they have no choice other than to start eating their dogs. Scott reasserts his authority.

Scott's team is gradually disintegrating and resentment amongst its members runs high. Scott intends to split his team in two: one travelling onwards to the Pole while the other returns to base.
