The documentary is about Project Possible, a plan by Nepali high altitude climber Nirmal Purja to climb all of the world's 14 highest peaks with an altitude greater than 8,000 metres (26,247 ft) (called eight-thousanders) inside 7 months (i.e. from late spring to late summer, before the winter season begins). The actual climbing took 6 months and 6 days between April 2019 to October 2019.
