When rogue junk collides with a television satellite 22 000 miles into space, blind cosmologist Harry Stones approaches film director Nathalie Thompson to make an investigative documentary.

Undeterred by Harry's lack of sight, their quest leads them from the peaks of Arizona to a mile-deep mine in Yorkshire, and finally to a launch pad in Kazakhstan. As more and more satellites keep falling out of the sky, their curiosity turns to fear. Forewarned of the possible outbreak of WWIII, can Harry and Nathalie prevent the most catastrophic space collision of all time?
