A new family is moving into the house next door. One of the back doors opens and a girl jumps out. Naima and Lisen quickly become friends and the very first day they meet they start their project; finding the perfect room for Lisen. In order to find the answer, they have to try sleeping in all the rooms of the house and grade them. The grownups get irritated with Lisen and Naima but the two of them just want to keep testing rooms—mostly so they can be together all the hours of the day.
