In 2019, an international coalition sets in motion a revolutionary project involving climate-controlling satellites known as "Dutch Boy." This ambitious initiative is initially placed under the control of the US government. When Dutch Boy successfully neutralizes a furious typhoon, Jake Lawson (Gerard Butler), the chief architect of the project, faces severe criticism from a Senate sub-committee for acting without authorization. Consequently, he is replaced by his brother, Max Lawson (Jim Sturgess), who is working under Secretary of State Leonard Dekkom (Ed Harris). Due to security lapses revealed during this transition, plans to transfer Dutch Boy from US oversight to an international committee come to a halt.
Fast forward three years, a United Nations team in Afghanistan stumbles upon a bizarre sight: a frozen village nestled in one of the hottest deserts on Earth. In this critical moment, an Indian engineer named Makmoud steals crucial data from the Afghanistan satellite right before an ominous incident sends him hurtling into space. He cunningly hides a hard disk with vital information in his personal locker before his life-altering "accident." After discussions with President Andrew Palma (Andy García), Max persuades Jake to embark on a mission to investigate the circumstances surrounding the Dutch Boy satellite and the apparent disaster it instigated.
While navigating the aftermath of the typhoon, temperatures begin to soar dangerously high in Hong Kong, resulting in a menacing Firenado that nearly takes the life of Cheng Long (Daniel Wu), who leads the Dutch Boy's operations in the region. Arriving at the International Climate Space Station (ICSS), Jake collaborates with station commander Ute Fassbinder (Alexandra Maria Lara) and her team to investigate the satellite responsible for the catastrophic event. However, an unexpected malfunction erases critical data necessary for deciphering the events that unfolded.
On Earth, Cheng's access is revoked, and he warns Max of a looming global catastrophe termed “Geostorm” if the faults within the system aren't addressed swiftly. As a determined Cheng makes his way to the United States while evading armed operatives, Jake and Ute venture outside the ICSS to recover a hard drive ejected during the chaos caused by Makmoud. They remain cautious, suspecting that a traitor exists among their crew.
Jake's suspicions lead him to appropriately inform Max about their findings, revealing a dangerous nexus of malfunctioning satellites causing extreme weather scenarios linked to a code named Zeus—a shocking proposal for manipulating climatic patterns. Meanwhile, a crisis escalates as Cheng meets a tragic end just as he attempts to communicate vital information to Max.
In a daring twist, Jake, Ute, and Ray Dussette (Amr Waked) discover evidence that exposes a pernicious virus tampering with login access to vital satellites. Jake grows increasingly convinced that President Palma has ulterior motives, suspecting that the leader intends to leverage Dutch Boy as a weapon rather than handing it over to the international committee. Realizing the stakes are monumental, he needs the kill code held by the President to execute a system reboot.
With chaos brewing across the globe, Max reaches out to his girlfriend Sarah Wilson (Abbie Cornish), a Secret Service agent, for assistance in obtaining the critical kill code. After a series of events where Japan faces fierce storms and Rio de Janeiro suffers from icy conditions, Max finds himself in a deadly game of survival as he seeks help from Dekkom, only to realize that his ally has turned adversarial.
Max and Sarah resort to extreme measures, seizing President Palma to shield him from compromised security agents. As they navigate through tumult, they reveal the insidious plans Dekkom has set in motion—eliminating America’s foes and angling for global dominance. Meanwhile, Jake grapples with a critical self-destruct process initiated by the virus in the ICSS, exposing the catastrophic spiral of events.
In a gripping finale, Jake valiantly holds the line as the crew evacuates, ensuring the system reboot is executed despite overwhelming odds. The effort culminates in a dangerous showdown, but unity amongst Jake and Ute proves pivotal as they manage to transfer satellite control to NASA just in the nick of time. The distress signal successfully leads to their rescue, and, months later, Jake rises as the lead engineer of a revamped satellite system now governed by an international body, bringing hope for a safer future.
