As a newcomer to a small Australian town, young Ned (Anthony Hammer, 12) needs to accept a dare to get accepted by the locals: he has to moon one of the teachers.
The same boy and a girl (9) get undressed in front of each other while changing for swimming, girl shown shirtless. The girl asks to see the boy's penis. He complies, but this is not visible to us. Small boy spies on them.
Before fate strikes the family, there is a cute scene where Han yi, the younger boy, is washed in the bathtub by Han Yeol, after soiling his pants. Little Yi is very lively and the washing scene evolves in a water fight.
