Athena-1, a space station owned by gene manipulation company Energyne, is destroyed after a laboratory rat mutates and wreaks havoc. Dr. Kerry Atkins, the lone surviving crew member, is ordered by CEO Claire Wyden to retrieve research canisters containing a pathogen. Atkins is able to flee in the escape pod when the station implodes, but due to damage from the rat it disintegrates upon re-entry, killing her. The falling pieces leave a trail of debris across the United States, including the Everglades in Florida, where a canister is consumed by an American crocodile, and a forest in Wyoming, where a gray wolf is exposed to the pathogen. Primatologist Davis Okoye, a former US Army Special Forces soldier and member of an anti-poaching unit, works at the San Diego Wildlife Sanctuary. He has befriended a rare albino western lowland gorilla named George, having saved him from poachers, and communicates with George using sign language and hand gestures. At night, one of the canisters crash-lands in George’s habitat, and George is exposed to the pathogen..
Davis Okoye (Dwayne Johnson) signs to George to calm the gorilla down, signing “It’s me.” The sign he makes is for “rock,” a reference to Dwayne Johnson’s nickname “The Rock.”
