Sam Flynn, the tech-savvy 27-year-old son of Kevin Flynn, looks into his father's disappearance and finds himself pulled into the same world of fierce programs and gladiatorial games where his father has been living for 20 years. Along with Kevin's loyal confidant Quorra, father and son embark on a life-and-death journey across a visually-stunning cyber universe that has become far more advanced and exceedingly dangerous. Meanwhile, the malevolent program CLU, who dominates the digital world, plans to invade the real world and will stop at nothing to prevent their escape.
When catastrophic climate change endangers Earth's very survival, world governments unite and create the Dutch Boy Program: a world wide net of satellites, surrounding the planet, that are armed with geoengineering technologies designed to stave off the natural disasters. After successfully protecting the planet for three years, something is starting to go wrong. Two estranged brothers are tasked with solving the program's malfunction before a world wide Geostorm can engulf the planet.
