In 1979, space station Skylab is decommissioned through atmospheric reentry, but an oxygen tank survives and lands in Western Australia. A farmer takes it and makes a makeshift Skylab museum around it.
In 2007, biochemist Dr. Hero Martins accompanies Pentagon bioterror operatives Robert Quinn and Trini Romano to the tank. It had been sent into space carrying an infectious fungus for study, and days before the three arrived, a heavily mutated fungus escaped the tank when the farmer attempted to clean it, infecting and killing him and many men in the surrounding area. Hero takes a sample of the fungus before a patch that she stepped on corrodes the boots of her hazmat suit, burns through, and infects her to control her actions. In a moment of lucidity, Hero commits suicide in front of Robert and Trini. The military incinerate the farm and the corpses, while the sample is taken to an underground cold storage vault at the Atchison Storage Facility in Kansas.
In the intervening years, the government has sealed the vault and rented the ground level section to a self storage company. In the present day, elderly client Ma Rooney enters her storage unit intent on committing suicide in a vault with her deceased husband's belongings, and night guards Travis Meacham and Naomi Williams start hearing a beeping alarm and try to discover its source. It turns out to be an alert for a malfunction in the vault's systems caused by a rise in temperatures, prompting Robert to be contacted in his Raleigh, North Carolina home by a military officer who when asked for a name, nicknames herself "Abigail". Robert is only given minimal support by official military channels, but convinces Abigail of the dangers brought by the fungus. She continues to use her personal phone to get him equipment and remain in contact throughout the mission. Abigail arranges Trini to meet Robert in Kansas, stopping first to pick up a device from her son's basement before dropping him off at the site.
Travis and Naomi head towards the sealed vault, where an infected rat king is outside the door separating them from a rapidly growing fungus trying to break out. Outside, Naomi's ex-boyfriend, Mike, arrives in his car to get her help after accidentally shooting his parent's cat. A cockroach that was infected in the vault gets outside and enters the trunk, reanimating the dead cat. When Mike lets the cat out, it kills itself by impaling its head on an antenna, spreading remains that infect both Mike and a deer. Returning to the ground level, Travis and Naomi see Mike and the deer have entered. Seeking to infect them with the fungus, the deer explodes and Mike chases them. The duo hides in one of the storage units and call the military. Abigail redirects them to Robert, who tells them that he is arriving and advises them to remain hidden.
However, their manager, Griffin, arrives with a biker gang to take smuggled televisions from storage. Travis and Naomi leave their hiding spot wanting to warn them to flee, but Mike infects most of the gang members as Griffin runs away. Before he get to the duo, Ma Rooney comes out of her storage unit and shoots him dead. Ma Rooney escapes the area while Naomi and Travis find Robert outside, who gives them a backpack nuke to be put outside the vault door and destroy the whole facility from within and eliminate any trace of the fungus. As the duo place the bomb (killing one of the infected along the way), Robert kills an escaping infected, but hurts his back and is unable to get up. Griffin goes outside and tries to steal Robert's car keys when an arriving Trini kills him. Travis and Naomi come back out and help Robert into Trini's car, driving away right as the bomb explodes.
Days later, Travis spends time with Naomi and her daughter, while Robert recovers in the hospital. He watches news reports praising him for preventing the outbreak, while condemning the military for obstructing his aid. A visiting Abigail, whose real name is Ishani, admits she leaked Robert's reports on the fungus to the press. Meanwhile, an infected deer vomits up the fungus in a forest.
