Yuadogjon plot
Man-Su, Poong-Ho, and Jae-Sup are three martial arts practitioners who run an unsuccessful gym. Man-Su finds a baby and brings it to the school. Of course, the three men can't take good care of the baby and the police want to take her to the local orphanage. The three men also grew up there and are now trying to do everything in their power to keep the baby and give it a good upbringing. What they don't know, however, is that the baby is the heiress of a large corporation and that's why a mobster wants to get the kid out of the way.
