Eight teenagers leave Sheffield with little idea of what lies ahead. Four are disabled and have only recently met their able-bodied team mates. Their destination is Kielder, a huge expanse of water and pine forest deep in Northumbria's rugged border country. Here they must undertake a succession of gruelling tasks in atrocious weather conditions. Two days later they should emerge unscathed, but with a new-found understanding of the differences in each other's lives.
