"Dudae-a-dae-a, I'll give you an old house, so come and buy me a new one" The children who left the orphanage and wandered around looking for a place to sleep come across an empty house in the mountains. The children try to make this house their hideout, but end up getting trapped in it... Will the children be able to get out of this house safely? What on earth happened in this house?
