Korean sci-fi/war film deals with a historic time warp in the DMZ. Two warring armies at loggerheads over a nuclear device are transported back in time to the 14th century. There, they meet a historic figure of a general who will later be found in all of their text books, General Lee. The general is very interested in their modern weapons and tactics but the soldiers need desperately to get back to their own dimension, lest the matter of the nuclear device become a world war.
