In early March 2007 three Spanish parachute jumpers flew over Antarctica in wingsuits – a feat that nobody had ever achieved before. The only previous attempt, by a US team, ended in tragedy. The film follows the meticulous preparation of the flight from the design of the wingsuits to the final stages of the jump – when the unpredictable weather conditions in Antarctica put the expedition on the verge of disaster. Beyond the adventure, this film captures a revealing story about one of the most primal human desires – to feel the exhilarating freedom of flying like a bird.
