Completely bereft of any survival skills or knowledge of the local customs or language, they're wandering the frozen wilds with just their mobile phone in the hope that it will prevent them freezing to death. But can the phone help them reach remotest Norway in order to get the best seats to view the hauntingly beautiful aurora borealis (Northern Lights)?

To triumph they'll need to squeeze every megabit out of their phones. They'll refer to online experts for assistance, and their social media followers for help. But for Russell, it will be hard to separate the good advice from the offensive - and somewhat ignorant - trolling!

They'll summon the full power of the internet to video call a sexy gun-toting survivalist for fire-starting advice, and beg their followers to identify the edible berries from the deadly. Their biggest challenge comes when their sat nav takes them to what seems to be the home of a family of serial killers. Has their phone sent them down the wrong path, or is the freezing cold getting to them? Can the internet conquer dog-sledding, indigestion-inducing reindeer blood pancakes, and the world's smelliest food - or should it just stick to helping us put up shelves and leave it at that?

He's climbing the Italian Dolomite Mountains without any training or experience. He's joined by internet comedian, Humza Arshad, who has hardly ventured out the UK, let alone conquered a mountain range - and one that claimed thousands of lives during WWI.

They'll be clinging to their mobile phones for dear life as they dangle from sheer rock faces, try to digest goat entrails and nose-dive a helicopter, all in an ill-fated bid to prove that internet is harder than mountain.
