Watch on SFlix. The film is based on the expedition of mountaineer Muhammad Ali Sadpara to K2 in Pakistan, which cost him his life in 2021 at the age of 45. The film opens with him passing the bottleneck with his companions, successfully climbing it, and then returning when he is caught in an avalanche or storm and ultimately loses his life. As his life fades from memory, the film shifts to flashbacks as he recalls the events of his life.
