New York, August 1974. A man is walking the sky.The city stands still in awe. Between the newly built Twin Towers the man is striding, twirling and showboating his way through the air. One hundred and ten stories below him, the lives of eight strangers spin towards each other. Set against a time of sweeping political and social change, from the backlash to the Vietnam War and the lingering sceptre of the oil crisis to the beginnings of the Internet - a time that hauntingly mirrors the present time - these disparate lives will collide in the shadow of one reckless and beautiful act, and be transformed forever.
