Query: Touching the Void

Based on Simpson's bestselling book, this harrowing, suspenseful docudrama recreates the events of Yates and Simpson's fateful, arduous climb, sparing nothing in the traumatic details: exposure to the elements, violent snowstorms, and an icy 150-foot crevasse Yates unwittingly pitched his crippled mate into--then abandoned, believing him dead. That Simpson, the narrator, survived is a miracle in itself, but hearing his jarring account of the escape couldn't be more engrossing. For visceral thrills, "Void" is the perfect armchair adventure.
