North- and South-Korea build an atomic bomb in a joint production. However, because of the pressure of several countries, they decide to hand over the warhead to the Americans. General Kang (Kim Seung-woo) of the north korean army doesn't accept his country's decision and steals the warhead with the help of some of his soldiers. Moreover, he takes scientist Kim (Kong Hyo-jin) as a hostage and tries to leave the country. Therefore south korean officer Park (Hwang Jeong-min) gets the order to stop him.
On a river the two parties finally clash and they engage into a gun fight, when suddenly a comet passes by. The next thing they know is that they have been catapulted 433 years into the past, as some chinese barbarians attack them, but are easily driven away by the soldiers modern weapons. Henceforth, they are glorified as the "Heaven's Soldiers" by the farmers they saved.
While physicist Kim starts to construct a theory about what happened and more importantly tries to figure out how to get back to their time line, the soldiers go on a search for the now missing warhead. As if it weren't enough thief Lee Soon-shin (Park Joong-hoon) somehow manages to steal their arms.
Interestingly enough, Lee proves to be legendary General Lee, who is supposed to beat the Japanese in a not so distant future. It's only that he is so much more different than what the Koreans expected. Park makes it his business to help his idol out whereever he can and to make him the person, who he is supposed to be in the history books. Soon enough Park and his men have the chance to deliver a battle against the invading barbarians. But can Lee live up to one's expectations?
