Based on the book of the same name by renowned screenwriter David Koepp (“Jurassic Park”), “Cold Storage” is a maddeningly unhinged and boisterously enjoyable B-movie experience. With plenty of gore and splatter, this zombie comedy’s status is largely elevated by the committed presence of A-listers like Liam Neeson, Leslie Manville, Joe Keery, and Georgina Campbell. Directed by Jonny Campbell, the film explores the hilarious and yet tense attempts of its lead characters to contain a parasitic green fungus.
Cold Storage (2026) Plot Summary & Movie Synopsis:
“Cold Storage” begins with a few introductory words that explain the operations of NASA’s Skylab, a breeding ground for notorious experiments. One such lab was decommissioned and destroyed. However, despite NASA’s confidence in cleaning up after itself, some debris from that lab survived. Years later—and 18 years ago from the current timeline—one such fragment was discovered in the Australian outback. A local farmer retrieved it, which turned out to be a cylinder. It stayed fine until he tried to clean it, when green, gooey junk started leaking. By the time Dr. Hero Martins (Sosie Bacon) arrived to address the issue, the entire population was taken hostage by the fungus.
Hero was joined by United States Army officers Robert Quinn (Liam Neeson) and Trini Romano (Lesley Manville). The three of them were horrified to find the deformed bodies of the fungus’s victims. It appeared that in the last stage, the fungus had its host swell up and explode to release the green goo for continuous propagation. As she took a sample of the fungus, Hero mistakenly stepped on the green goo. It managed to enter her bloodstream through her boots. The fungus took over the host’s nervous system and told Hero to contact others and spread. However, Hero managed to shoot herself, giving Robert and Trini a chance to contain the fungus.
Robert and Trini sealed the fungus sample in cold storage at Kansas’s Atchison Facility. Years passed. Now, in the present timeline, the military sold it off. Privately owned, it operates as a storage rental facility, guarded by night-shift duo Travis “Teacake” (Joe Keery) and Naomi (Georgina Campbell). The old customer, Mrs. Rooney (Vanessa Redgrave), arrives under the pretext of checking her unit. Her true motive for the late-night visit is to kill herself amid her late husband’s cherished mementos. While escorting her to the storage unit, Travis hears an electronic beep. He grabs Naomi, and they investigate the sound together.
They trace the source to a map leading to a hidden underground vault. Naively, they follow it. Inside, a terrifying scene awaits: a locked chamber with green goo oozing from the door. Rats, infected by the fungus, deform grotesquely—devouring each other, tails fused into a macabre rat-king. Travis and Naomi flee the scene, with Naomi frantically calling the military numbers she found posted outside the forbidden, fungus-containing vault door. Meanwhile, in North Carolina, an aged but still formidable Robert receives an alert on his phone. It is the call from one military officer who has received the signal that indicates the fungus’s breach. Robert has been anticipating this all along.
Robert instructs Officer Abigail to review his decades-old report—filed when the fungus was stashed away rather than destroyed. Her boss, the current department head, dismisses it as routine. But Robert convinces Abigail it’s far graver: mishandled, it could doom humanity. She pledges support, even bending protocol. With Abigail’s aid, Robert races to Kansas, greeted by none other than Trini. He patches in with Naomi and Travis, who contacted the military earlier—Abigail forged the link. Unbeknownst to all of them, a storm is gathering outside the storage facility. In the form of Naomi’s ex, Mike, and a deer.
Cold Storage (2026) Movie Ending Explained:
How Did the Fungus Spread in the First Place?
Even before Naomi and Travis encounter the grotesque rat-king, the fungus has already begun its deadly work outside the facility. Mike, who barged in at Naomi’s workplace, becomes the first human victim. A quick flashback shows exactly how the fungus got out. Deep inside the storage unit, just before the rats succumb to the green goo, a lone cockroach falls victim first. Zombified, it navigates the vents to the parking lot, only to be stomped by Mike’s car tire. Yet the fungus latches onto the tire. From there, it infiltrates a drunk Mike through a cat… and then a deer.
Zombie Mike, accompanied by a zombie deer, ventures inside. The fungus inside Mike keeps urging him to infect others. Upon seeing Naomi and Travis, Mike expresses his desire to vomit on them. Both realize the danger and run away. Zombie Mike follows them. Naomi and Travis take shelter inside an open unit, hoping Mike won’t notice. However, Travis knocks over some items. The noise draws Mike to their location. Mrs. Rooney saves them—she shoots Mike in the face. It doesn’t kill him, but it gives Travis and Naomi a chance to escape. Travis escorts Mrs. Rooney outside and takes her gun with him.
What Happens to Griffin and His Gang?
To make matters worse, Travis and Naomi’s manager, the absolutely uncouth Griffin, decides to do his smuggling work on the same night. Griffin has a pile of stolen televisions that he plans to move that very night. Griffin’s gang goes inside to witness the mayhem first-hand. At first, Griffin is sure Travis had screwed something up. However, after seeing the burst body of the deer, swimming in green goo, he suspects something weirdly wrong has happened inside his facility. Still, the gang ventures downstairs to get the TVs. There, they are greeted by Mike. Now more deformed, and more dangerous.
Mike finally gets the chance to do what he has been tasked to do. He vomits all over three of Griffin’s gang members. Then he locks them inside the storage unit. Once again, he focuses his attention on finding Naomi. But before he can, his time comes. His chest bursts open. The fungus goo leaves his body, now having exhausted Mike’s utility fully. Griffin, who was upstairs when this happened, comes downstairs and attacks Travis, believing him to be the culprit. Griffin asks Travis to open the storage unit and release his friends—the ones Mike vomited on. Despite Travis’ warning, Griffin opens the door and sees three of his friends deformed. One of whom bursts in front of his eyes.
Did the Fungus Die Once and for All?
Meanwhile, Robert reaches the facility after he and Trini have recovered a nuclear bomb that the two of them stashed for this very purpose. Robert meets Naomi and Travis. He highlights how the fate of the world now depends on the three of them. Naomi and Travis agree to drop the bomb inside the underground vault where the fungus is stored. The theory is that if they detonate it underground, it will only take the facility down. As Naomi and Travis attempt to drop the bomb, Robert stays outside to assassinate any infected survivors. He probably intended to kill Naomi and Travis, too.
However, before Naomi and Travis, Griffin comes out of the door with two of his infected friends. Robert kills all of them. But during the fight, his bad back gives way. He lies on the concrete road, unable to move, while the green goo from one of Griffin’s friends reaches towards him. Trini, however, makes the save. Just in time for Naomi and Travis to come out of the facility, too. The four of them drive away as the bomb goes off. Their car just manages to escape the resultant sinkhole.
A couple of days later, we see Abigail visiting Robert in the hospital. Robert recovers, and his work is vindicated. Naomi and Travis are together now. However, just before the credits roll, we see one of the deer in the jungle look at the camera and vomit green goo. Now, this could just be a cool way to finish the film. But chances are that the parasitic fungus did survive. Remember when it infected Mike—it was through the cat-bursting. The fungus was shown to drop on Mike and one of the deer. However, a few more deer were grazing nearby. So, it is not entirely impossible that the fungus survived.
