Documentary based on Philippe Petit's autobiographical book To Reach the Clouds: My High Wire Walk Between the Twin Towers. In August 1974, French wire-walker Philippe Petit spent nearly an hour walking, dancing, kneeling and lying on a wire which he and his friends had strung in secret between the rooftops of New York's Twin Towers. Six years of intense planning, dreaming and physical training fell into place that morning. Already an accomplished wire-walker, Petit had caught sight of an article about the planned construction of the Twin Towers while in a dentist's waiting room in 1968, and at that moment an obsession was born. He spent every waking moment since that day plotting the details of his walk (which he called 'le coup') and gathered a team of people around him to assist in the planning.
