"Documentary thriller about warfare in a world without rules - the world of cyberwar. It tells the story of Stuxnet, self-replicating computer malware, known as a 'worm' for its ability to burrow from computer to computer on its own. In a covert operation, the American and Israeli intelligence agencies allegedly unleashed Stuxnet to destroy a key part of an Iranian nuclear facility. Ultimately the 'worm' spread beyond its intended target."
