This drama commemorates the soldiers who gave their lives in the Korean War, fought between North and South Korea between 1950 and 1953, and is designed to remind people that the heavy cost of human lives far outweigh any national glory. Lee Hyun Joong is a South Korean squad commander and war veteran who is dedicated to protecting the lives of the soldiers serving under him, despite his jaded outlook. His chance meeting with Lee Tae Ran on the battlefield stirs memories of the past, but she is now a lieutenant of the North Korean army.
