When catastrophic climate change endangers Earth's very survival, world governments unite and create the Dutch Boy Program: a worldwide net of satellites surrounding the planet, that are armed with geoengineering technologies designed to stave off the natural disasters. After three years of successful protection, something starts to go wrong. Two estranged brothers are tasked with solving the program's malfunction before a worldwide Geostorm can engulf the planet.
When the network of satellites designed to control the global climate starts to attack Earth, it's a race against the clock for its creator to uncover the real threat before a worldwide Geostorm wipes out everything and everyone.
