Novye druzʹja Onneli i Anneli

A new house is being built across from the houses of Onneli and Anneli. The new house will be an orphanage run by Minna Pinna, the former housekeeper if Anneli's father. The strict Minna Pinna runs the orphanage housing 20 children like a prison. One morning, Onneli and Annaeli meet Pekki, a boy who escaped the orphanage in its former building and has now come to the new location to free his brother who is still there as well as the other orphans. The girls decide to help Pekki rescue the orphans from Minna Pinna, which turns out to be more complicated than expected.
