Sparks fly between Academy Award® winners George Clooney and Nicole Kidman who join forces to stop a nuclear terrorist in this explosive action thriller. When a train carrying atomic warheads mysteriously crashes in the former Soviet Union, brilliant U.S. nuclear specialist Dr. Julia Kelly (Kidman) discovers the accident is really part of a diabolical plot to cover up the theft of the weapons. Assigned to help her recover the missing bombs is crack Special Forces Colonel Thomas Devoe (Clooney), whose brash, take-no-prisoners style clashes with Kelly’s more diplomatic approach. Putting aside their personal differences – and budding romance – the two begin a tumultuous partnership as they track down the stolen weapons, following a deadly trail of espionage and intrigue that culminates in an unauthorized air assault inside Russian territory. Now, it’s a race against time to uncover the last missing warhead...before it’s too late.
