 Luc Devreux and Andrew Scott are US soldiers who kill each other in Vietnam when Devreux interferes with Scott s slaughter of a friendly village. Listed as MIA, they are actually flash-frozen and shipped to a top-secret facility where a team of scientists led by Colonel Perry turn the two, along with other select specimens, into super-soldiers known as "UniSols." While helping foil a terrorist takeover of the giant McKinley Dam, Devreux starts having flashbacks to his former life, and makes a break from his colleagues. The increasingly human Devreux teams up with TV reporter Veronica Roberts, while they are chased across much of the Midwest by Scott, and also by Perry and the police, who capture them long enough for Scott to find them. After a chase, thinking that they killed Scott in a truck crash, Veronica takes Devreux home to his parents in Louisiana, only to have Scott catch up with them for a brutal confrontation.
