The Devil's Climb | Preview (National Geographic)

From Plimsoll Productions, THE DEVIL’S CLIMB follows world-class rock climbers Alex Honnold and Tommy Caldwell on an epic expedition to tackle one of the most daunting challenges of their careers: summiting the infamous Devil’s Thumb, a sinister tower and legendary 9,000-foot peak in the Alaskan wilderness surrounded by old-growth rainforest and known as one of the most dangerous mountains in North America.

Alex and Tommy are two of the greatest rock climbers of all time — and best friends. Together, they set off on an emotional and physical journey, traveling 2,600 miles by bicycle, sailboat and on foot through the American West, Canada and Alaska to a daring climb of the Devil’s Thumb.

For Tommy, regarded as a pioneer in the sport and one of Alex’s heroes, this expedition is a chance to make a heroic comeback from a career-threatening Achilles injury, making the expedition’s success uncertain.

For Alex, this climb is among the greatest adventures of his life, a testament to his relentless drive to achieve the impossible as well as his commitment to Tommy’s return to climbing. The two friends have a rich shared history of adventurous speed climbing and a record-setting partnership.

Directed by fellow climber Renan Ozturk, witness the breathtakingly extraordinary adventure as Alex and Tommy attempt to accomplish the first-ever single-day traverse of all five peaks of the Devil’s Thumb massif, pushing their bodies and bond to the absolute limit.

Thrilling documentary special THE DEVIL’S CLIMB, which is set to premiere Sunday 22nd December at 9pm on National Geographic.
