Four teachers prepare for a once-in-a-lifetime trip to Antarctica to undertake science projects and report back to their pupils. But what toll will it take on both them and their families? We follow the expedition from their first training session in Norway on the largest ice-cap in Europe, through their fundraising to earn the £10,000 each they need to go, all the while holding down a full-time teaching job. While the four teachers selected relish the chance to use their experience to inspire pupils back at home in England, they soon find out just how much blood, sweat and tears it takes to undertake such an expedition.
