Vertical Limit Plot Summary: A high-adrenaline tale of young climber Peter Garrett, who must launch a treacherous and extraordinary rescue effort up K2, the world's second highest peak. Confronting both his own limitations and the awesome power of nature's uncontrollable elements, Peter risks his life to save his sister, Annie, and her summit team in a race against time. The team is trapped in an icy grave at 26,000 feet - a death zone above the vertical limit of endurance where the human body cannot survive for long. Every second counts as Peter enlists the help of a crew of fellow climbers, including eccentric, reclusive mountain man Montgomery Wick, to ascend the chilling might of the world's most feared peak to save her.
