Most people don’t know that Finns live in every house. They are furry creatures that appear in the human world to take care of a house and guard the stove. Finnick is a young Finn who doesn’t have that responsibility. He only plays pranks in his house and therefore none of the families want to stay in his house for a long time. Everything changes when a new family arrives at Finnick’s house, whose tricks have never worked. He meets 13-year-old Christine and begins to experience incomprehensible events in the city with her. Finnick and Christine, so different from each other, must come together and work together to solve the mystery of events and save the city.
