After the Vietnam War, the US government carried out a top-secret scientific project. Scientists froze the bodies of soldiers who died in the Vietnam War, implanted computer chips, entered war programs, and transformed them into a new generation of war robots-"space warriors". These robots have no emotions and previous memories, only cold killing weapons. Soldier Luke (Jean-Claude Van Damme) and squad leader Andrew (Dolph Lundgren) are two of them. They were sent to participate in a new war. During the war, the chips of the two suddenly went wrong, causing both of them to recover their previous memories. Luke remembered that it was Andrew who suddenly changed his temperament and killed all his subordinates and prisoners during the Vietnam War. The female reporter Robles (Ally Walker) who accidentally broke into the US military base accidentally learned the secret of the US military. Originally, Robles could not escape death, but Luke rescued her at the critical moment. So, the US military sent all the space warriors to start chasing the two.
