Romesh Ranganathan heads to one of the coldest environments on earth. He gets an insider's guide of the Canadian Arctic and finds out if his preconceptions about it are right.

A year ago, Romesh Ranganathan visited the Arctic to film a Christmas episode of the Misadventures of Romesh Ranganathan. It was the hardest trip he has taken in his life – it was minus 40 degrees, he had to camp in a tent on a frozen ocean and he had to go to the toilet in a bin bag. This year, he has agreed to do another Christmas episode - on the strict understanding that he will not go anywhere cold.
