For over a century the camera has been war's most efficient spy, keeping watch over the enemy, helping to predict enemy movements and guiding missiles to their targets. Now from its position in space camera has brought the earth and all its battlegrounds under constant and silent surveillance. But is the camera and its all-seeing eye a force for good or evil? How often has the information provided by the camera been misinterpreted, how often has it misled with deadly consequences ? Nothing stops the camera now, the camera and its related imaginery can see through clouds and at night, though it can't tell the difference between truth and the lie. 'Eye on the World' traces the rise of the camera from the balloon tethered above the enemy lines to its position in orbit. Precise Media Productions for Discovery Networks Europe
