Haunting Words from One of the Most Daring Antarctic Adventures of All Time

"We were helpless intruders in a strange world."

In 1914, Sir Ernest Shackleton and his crew embarked on an ambitious expedition: completing the first land crossing of the Antarctic continent. Six weeks into their voyage, they were left stranded after their ship, the Endurance, was trapped and sunk by crushing pack ice. With no chance of rescue, the crew began an 18-month battle for survival in one of the most extreme environments on earth. Remarkably, every member of the 28-man crew survived the ordeal and their saga remains one of the world's greatest adventure stories of human endurance and bravery.

Now, more than a hundred years later, filmmaker Glen Milner is journeying to the frozen southern waters to retrace the steps of this legendary adventurer. In Letters of Fire, take a visual odyssey through Antarctica's unforgiving landscape as actor Dominic West brings to life the haunting journal entries of Shackleton's doomed voyage.
