When Killian, the world's strongest cross-country runner, was still a child, he recorded many of the high and steep mountains in the world in his notebook, hoping to conquer them one by one when he grew up. When he completed all the mountains in his notebook, in May 2017, he started the "Peak Life" plan: climbing Mount Everest twice in a week without carrying oxygen tanks, ropes and no companions. This film leads the audience to witness Killian's legendary career and also exposes his unknown vulnerability, fear and self-doubt.
