Plot
Kim, an elementary school teacher, convinces her boyfriend, Yong-ho, a Taekwondo master, to take his students on a self-discipline training trip. He agrees enthusiastically and Kim, Yong-ho and the Taekwondo students head for Galchimal Island. The students train Taekwondo martial arts vigorously and learn the meaning of discipline and self-denial as the seagulls fly over the beautiful island. Meanwhile, a young space cadet named Gilbo makes an emergency landing on the island while flying through space from his space nation Sirius. At first the young boys are suspicious of Gilbo but they soon befriend him when they find out he is not much different from them. But the students are devastated when Gilbo and Kim are kidnapped by a gang of delinquent youths. Using everything they have learned so far, the students and Yong-ho go up against the bad guys.
