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.
