Plot
Lee Jang-woo (So Ji-sub) would do anything for his childhood sweetheart Soo-yeon (Kim Ha-neul). When Soo-yeon's family falls on hard times, he joins the army in order to earn money to pay for her tuition. While Jang-woo is on his tour of duty, Soo-yeon studies hard and spends her time helping injured soldiers as a doctor. She patiently awaits Jang-woo's return, but one day receives word that he has died in combat. Fate brings another man into her life: Shin Tae-ho, a handsome and generous officer who graduated from the army academy at the top of his class. Though she can't forget Jang-woo, Soo-yeon finally decides to leave the past behind her and marry Tae-ho. On the eve of their wedding, Jang-woo suddenly appears again, revealing that the death notice had been a mistake. He had, in fact, been counting the days until he can return home and reunite with his lover. The next morning - June 25, 1950 - the North Korean army invades South Korea, marking the start of the Korean War. With their lives and love already in turmoil, both Jang-woo and Tae-ho are sent north to the battlefield.
