In a dramatic attempt to bring attention to climate change, an international expedition led by renowned explorer Will Steger embarked on the first-ever coast-to-coast expedition across Antarctica in 1989. Six men and their sled dogs braved howling storms, sub-zero temperatures, snow crevasses, and other perils as they traversed the icy terrain. Tasha Van Zandt’s enthralling feature debut catches up with Steger 30 years later as he revisits the frigid continent, deftly weaving his contemporary journey with rare, dynamic footage of his original, treacherous seven-month odyssey.
