“Overcast”, written and directed by Matthias Hancke, is a groundbreaking documentary about a phenomenon that most of us would consider normal: Jet contrails that spread into clouds, covering the sky and blocking the sun. For some people however, these trails are the biggest environmental crime in the history of mankind.
Based on ideas first outlined in 1974, scientists have developed the basic technology necessary for climate control. Jet planes would be deployed, dispersing large amounts of harmful chemicals into the atmosphere to reflect sunlight back into space.
However, what if this technology known as geoengineering has already been fully implemented for many years, with neither public consent, nor disclosure?
