Please answer the following question: I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: The Peacemaker Movie plot: In an Eastern Orthodox church in Pale, Bosnia and Herzegovina, an unidentified man (later revealed to be a Bosnian minister) is murdered after being paged to meet someone outside. (The murderer called him "minister"). At a missile base in Chelyabinsk, Russia, ten SS-18 ICBMs are being decommissioned. Ten nuclear warheads are loaded onto a train and sent to a separate site for dismantling. However, a corrupt high-ranking Russian general, Aleksandr Kodoroff, has other plans. Along with a rogue tactical unit, he kills all the other soldiers on board the transport train and then transfers nine of the warheads to another train. Kodoroff then activates the timer on the remaining warhead and sends the transport on a collision course with a passenger train. Minutes later, the 500-kiloton warhead detonates, killing the survivors and delaying an investigation. The detonation immediately attracts the attention of the U.S. government. White House nuclear expert Dr. Julia Kelly (Kidman) believes that Chechen terrorists are behind the incident. U.S. Army Special Forces Lieutenant Colonel Thomas Devoe (Clooney) interrupts her briefing to suggest that the crash and detonation were staged to hide the hijacking of the other warheads on board. A call to Devoe's long-time friend and Russian counterpart, Dimitri Vertikoff (Mueller-Stahl), adds credence to his hypothesis and he is assigned as Dr. Kelly's military liaison. Kelly and Devoe try to track the terrorists through an Austrian trucking company which is a front for the Russian Mafia. When the Mafia realizes they are U.S. government agents, they send thugs to kill them. Vertikoff, thinking he can pay them off, is soon killed. The Mafia then chase Devoe. He is able to outwit them with his superior driving skills. He kills most of the assassins, and he and Kelly escape. Information from the trucking company shows that the nukes are bound for Iran. Spy satellites place the truck in a traffic jam in Dagestan, Russia, and Devoe uses a ruse to identify it. The satellite, tracking... My question: Who activates the timer on the remaining warhead?
A:
Kodoroff
