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.

Everyone Romesh has ever met has told him how amazing the Scottish islands are - but nobody he knows has actually ever been there. Now, in a year when travel abroad has been all but forbidden, he is heading to the Hebrides to find out if you can really have a proper adventure so close to home, spending a week visiting the isles of Skye, Harris and Lewis. Guiding him through the journey is Donald Macsween, or Sweeney to his friends, a local crofter from the far north of Lewis - a place that lies as far north as Greenland.

Romesh catches up with friends from Zimbabwe, Bosnia and the Sahara, revisiting some highlights and introducing never-before-seen moments, like trying to recreate a horror film in the desert.
