The compelling story of 30-year-old climber Tom Ballard who disappeared on one of the Himalayas' most deadly mountains, Nanga Parbat, in February 2019. Tom was the son of mountaineer Alison Hargreaves, who perished on K2 in 1995. Mother and son, two of the greatest climbers of all time, died at almost the same age in neighbouring mountain ranges, both doing what they loved best. They now lie forever encased in the ice of two of the world’s highest mountains. Left behind to cope with the enduring tragedy are Tom’s sister, Kate, and their father, Jim.

On some peaks in 2003, the statistics are impressive. For the K2 dubbed "wild mountain" or "ruthless mountain", only 240 reached the summit and more than 60 perished in the ascent. An unimaginable rate of one death in four to survive. And these statistics are even worse At the start of the 2004 climbing season, only five talented and determined women had reached the 8,616-meter summit of K2, but only two made it out alive. , they too perished while climbing other peaks of 8000 meters, these five women all disappeared in the mountains.
