A father does his best to maintain an ordinary family life while his two young daughters do what kids their age all around the world do: play. However instead of relying on their imagination Milla and Meri use their technical expertise to build fantastical things and just bend the reality when necessary. Giant robots, roaring dinosaurs and ticklish shrink rays galore. Meanwhile the father takes is easy, drinks his coffee and makes sure that healthy ways of living are maintained. Bedtimes are to be observed regardless of time machines and there are always vegetables for meals.
