Terrorists kidnap the Russian Prime Minister's 2 kids, take Chernobyl nuclear power plant and threaten to blow up a reactor. 4 Universal Soldiers go in but are no match to a Next Gen. UniSol. Luc/JCVD goes in but faces 2 NGUs.
With stolen top-secret technology, terrorists have created a next-generation Universal Soldier - an elite fighter genetically altered into a programmable killing machine. With this "UniSol" (Former UFC Heavyweight Champion Andrei "The Pit Bull" Arlovski) leading the way, they seize the crippled Chernobyl nuclear reactor, threatening to unleash a lethal radioactive cloud. The only one who can stop them is Luc Deveraux (Jean-Claude Van Damme), a UniSol who's been decommissioned for years. Reactivated and retrained, Deveraux must make a full-out assault on the heavily armed fortress. But inside, he'll discover not one but two of these virtually indestructible warriors. Andrew Scott (Dolph Lundgren), Deveraux's vicious UniSol enemy from the original Universal Soldier, has been secretly reanimated and upgraded. Now, these elite fighters are locked, loaded and programmed to kill; and the fate of millions hinges on this high-action showdown.
When terrorists threaten nuclear catastrophe, the world's only hope is to reactivate decommissioned Universal Soldier Luc Deveraux. Rearmed and reprogrammed, Deveraux must take on his nemesis from the original Universal Soldier and a next-generation "UniSol".
- A group of terrorists led by Commander Topov (Zachary Baharov) kidnap the Ukrainian prime minister's son and daughter and hold them hostage, demanding the release of their imprisoned comrades within 72 hours. In addition, they have taken over the crippled Chernobyl Nuclear Power Plant and threaten to detonate it if their demands are not met. It is revealed that among the ranks of the terrorists is an experimental Next-Generation UniSol (NGU) (Andrei Arlovski) who was smuggled in by rogue scientist Dr. Colin (Kerry Shale) U.S. forces join up with the Ukrainian army at the plant, but quickly retreat when the NGU slaughters most of them effortlessly. Dr. Porter (Garry Cooper) Dr. Colin's former colleague on the Universal Soldier program, revives four UniSols to take down the NGU, but they are systematically eliminated.
Former UniSol Luc Deveraux (Jean-Claude Van Damme), who is undergoing rehabilitation therapy in Switzerland with Dr. Sandra Fleming (Emily Joyce) with the goal of rejoining society, is taken back by the military to participate in the mission. As the deadline nears its expiration, the prime minister announces the release of the prisoners. The terrorists, having gotten what they wanted, rejoice and shut off the bomb. Dr. Colin, however, is not pleased with the outcome, as he feels his side of the business is not done. As the NGU is programmed not to harm the terrorists, Dr. Colin unleashes his second UniSol: a cloned and upgraded version of Andrew Scott (Dolph Lundgren) - Deveraux's nemesis - who quickly kills Commander Topov. However, Dr. Colin never considered Scott's mental instability, and he is killed by his own creation. Scott then reactivates the bomb before heading out to hunt the children.
In the midst of the chaos, Capt. Kevin Burke (Mike Pyle) is sent in to infiltrate the plant and rescue the prime minister's children. He is successful in locating them and leads them toward safety. On their way out, they encounter the NGU. The children flee as Burke tries in vain to hold off the NGU, who stabs him to death after a brutal fight.
With 30 minutes remaining on the bomb's timer, a re-conditioned Deveraux is geared up and sent to the plant, where he kills every terrorist he encounters. He searches the buildings and finds the children cornered by Scott. Scott, who has distorted memories of Deveraux, is about to kill the children when Deveraux attacks and a grueling fight ensues. In the end, Deveraux impales Scott on the forehead with a lead pipe and fires a shotgun through it, blowing his brains out.
As Deveraux escorts the children to safety, they are attacked by the NGU. Deveraux and the NGU take the fight to the site of the bomb, with less than two minutes remaining. During the melee, Deveraux removes the detonator and jams it in the back of the NGU's uniform as they both jump out of the reactor chamber. NGU pulls the detonator off his back as it explodes, taking him with it. U.S. soldiers quickly arrive on the scene and tend to the children as Deveraux leaves. Burke's body is placed in a black bag and taken away, as well as recovered pieces of the NGU.
In Langley, Virginia, Burke's body is shown stored in a cryogenic chamber as a new UniSol, along with multiple clones made of him.
