Tom lives in a camper van together with his elderly father James. His mother, the famous climber Alison Hargreaves, lost her life coming down K2 when Tom was only 6 years old and since then the boy has tenaciously pursued the dream of becoming a mountaineer and of climbing the six great north faces of the Alps in a single winter. Nobody has yet managed to do so with this timescale and he wishes to become the first. Accompanied by his father, who drives a white van, Tom will face any risk in order to fulfil his dream.
