A Sad Story of Danjong

A famous general who defeated Japanese invaders with the world's first iron ship, 'Turtle battleship' during Chosun dynasty, was intrigued against by many villainous retainers. Even when he was reduced to a much lower rank, he served in the war worrying about the nation's wellbeing. This film depicts General Lee Sun-Shin who is probably the most famous general in Korean history, based on his 'Wartime Diary.'

Ten years later, Cheong-myeong, 12 year-old son of Lee Won-guk who survived the killing, seeks revenge on Seong-dal. Jeong-a, daughter of Yu Cheong who also survived, trains in martial arts and sets out to find her enemy, too. Cheong-myeong and Jeong-a, who were betrothed when they are children, join together to kill Bak Seong-dal.
