Plot
In 2030, Earth is under siege by an alien invasion with many alien warships, attacking various cities and resulting in the deaths of thousands of lives. Other countries attempt to refight the aliens with conventional weaponry but were ineffective against the ship's advanced deflector shields. The President issued an emergency meeting at the United Nations where world leaders, senators and representatives gathered to discuss on how to defeat the threat. The chairman of the joint chiefs, Carter MacMillan suggested to launch a nuclear counterstrike but that would kill them too.

However, a renowned scientist from Germany, Isaac Kleinberg came before them with a sign of hope; a recovered one piece of the saucers that the tanks manage to break off. This inspired the masses to develop a. super weapon to end the invasion and the president and joint chiefs agreed to follow along with his plan. Dr. Kleinberg along with many leading scientists and engineers to work together in hidden laboratories around the world created a series of state-of-art pulse generators in a proximate 2 years and the United Nations was formed to fend off the invaders to buy them time. 80 generators were built and are then placed upon key famous landmarks around the world. Activated in unison, the generators emitted a massive EMP wave that crippled the warships and fighters, causing them to fall. The invaders were defeated, and humanity was saved, with many mourned for their losses while some rejoiced and celebrating their victory in relief that it was finally over. Unbeknownst to them, the downed ships started leaking out glowing green ooze into streams, gutters, and oceans around the world never knowing that the seeds of their fallen enemy would bear fruit to a newer threat.

5 years later in 2035, Athena-1, a research space station owned by gene-manipulation company Enzyme, which has been experimenting with Alien Green, a green sludge similar to Kaiju Blue, is destroyed after a laboratory rat mutates and wreaks havoc. Harv Kleinberg, the lone surviving crew member, manages to escape in a pod when the station implodes, along with pathogen canisters that Enzyme CEO Mondi Sheppard (Ryan Reynolds) orders him to retrieve, but the pod disintegrates, killing him and leaving a trail of debris across the world. One canister is swallowed by an Bengal Tiger in India, one is exposed to an American Bald Eagle, one near the waters between Washington and British Columbia which is exposed to a southern resident orca and another lands in a Wyoming forest where a wolf is exposed to the pathogen.

Marine Biologist John Tanner (Matt Damon), a former Green Beret and member of an anti-poaching group, works at the Atlanta Zoo alongside former CIA operative, Tobias Jones (Brad Pitt). He has befriended a lion named Clarkson that he saved from several poachers in Kenya back in 2033 when they killed his mother. One of the canisters crash-lands near Clarkson and he is exposed to the pathogen.

As Clarkson considerably larger and becomes more aggressive, Tanner is contacted by genetic engineer Dr. Isaac Kleinberg, who explains that the pathogen was developed by Enzyme to rewrite genes on a massive scale. He had hoped to advance research on CRISPR following human victory in the Great Solar War as a potential cure for diseases, but discovered Enzyme's plans to use it as a biological weapon and was falsely incarcerated, during which his terminally ill father died. Clarkson escapes from captivity and goes on a rampage at the preserve. Clarkson is soon captured by a government team led by Agent Cole Bertrand (Nolan North) and put on a Airbus A400M Atlas airplane. Meanwhile, Mondi and his sister Heather oversee a mercenary team's attempt to capture the mutated tiger, Garcia, in India, which goes awry, and the entire team is slaughtered.

Mondi, hoping to capture Garcia and use Clarkson to cover up her plot, uses a massive transmitter atop the Transamerica Pyramid to lure the animals – engineered to respond aggressively to a certain radio frequency – to San Francisco, unconcerned about the massive risk to civilian lives this poses. Clarkson reacts violently to the sound and crashes the plane, though Tanner, Jones, and Bertrand parachute to safety. Clarkson survives the crash and joins Garcia as they make their way to San Francisco, while Tanner and Tobias are aided by Bertrand in stealing a military helicopter in pursuit.

They arrive to find Clarkson and Garcia rampaging through the city as the military struggles to contain them. The situation worsens when the mutated bald eagle, Ethan, and the mutated orca, Sarah, joins the duo, causing even more casualties. Planning to steal an antidote to turn the animals back to normal, Tanner and Jones infiltrate Enzyme's base of operations at the tower and take several vials of it, but are caught by the Sheppard's as Mondi reveals that the antidote only eliminates the animals' enhanced aggressiveness rather than reversing the other effects and shoots Tanner, but he survives. When Clarkson climbs to the top of the tower, Mondi orders Tanner to distract it while she attempts to escape with Jones at gunpoint. Jones slips a vial into Mondi's handbag and pushes her toward Clarkson, who devours the terrorist along with the vial, returning him to his normal personality. Down below, Bertrand takes incriminating evidence from Heather, who is crushed to death by falling debris. As the damaged tower topples, Tanner and Jones survive by crash-landing a helicopter on the Oracle Park.

Tanner stays to help Clarkson defeat the other animals, while Jones and Bertrand rush to prevent the military from deploying a B83 Nuclear bomb against them. Clarkson battles against Garcia, whom Tanner tricks into advancing towards Ethan, who decapitates her using his jaws. Lizzie chases Davis, but George intervenes in time for Davis to incapacitate her using grenades. However, Lizzie survives and overpowers George, who is impaled by a rebar. Davis distracts Lizzie using a fallen Apache attack helicopter, but is nearly killed before George pierces Lizzie through the eye with the same rebar, killing her.
