With the rapid emergence of digital devices, an unstoppable, invisible force is changing human lives in ways from the microscopic to the gargantuan: Big Data, a word that was barely used a few years ago but now governs the day for almost all of us. This award-winning film explores how the real time visualization of data streaming in from satellites, billions of sensors and GPS enabled cameras and smart phones is beginning to enable us, as individuals and collectively as a society, to sense, measure and understand aspects of our existence in ways never possible before. Together these devices are helping create a new kind of planetary nervous system. This massive gathering and analyzing of data in real time is also allowing us to address to some of humanity biggest challenges, including pollution, world hunger, and illness.

Whether earthquake, terrorism, flood or just crime, it's the geology, politics and social makeup of the megacities that make them some of the most profitable and dangerous places to live.
