Accidental Climber (2019)

Jim Geiger, a retired forest ranger and amateur mountaineer, attempts to become the oldest American and first great grandfather to summit Mt. Everest, aged 68. His transformation from a weekend hiker to attempting one of the most extreme and physically demanding feats known to man is driven by a desire to prove that age is just a number. What ensued, however, forever changed Jim's life.
