A small detachment that suffered at the hands of the invader of their native lands is hiding in a mysterious forest. On one of the harsh winter nights, they find a stranger dying more often. The leader of the detachment, Il Kang, a former army general, Carrie, immediately perceives her with hostility - he does not believe that the girl who identified herself as Elena lost her memory, and also cannot explain how she was able to penetrate the Gloomy Forest. In addition, the mysterious stranger quickly unraveled the terrible secret that Il Kang hid from his subordinates, becoming a target for the leader and his lover - a spy from the Imperial Court. Elena was defended by Il Kan's best friend, Asa Kai, who could not forgive him for the death of his bride. Whose alliance will win, and will Elena be able to save the detachment from the mortal danger that Il Kan is fraught with?
