11-year-old Tommy (Alessandro Morris) lives in Rome with his sister Viola (Matanobili) and his father Renato (Jim Rossi Stewart). The three of them often quarrel with trivial family problems, but it's sweet. Tommy likes to climb on the roof and overlook the city. He likes playing football, but his father asks him to learn to swim and sprint for the championship. He often loses his temper when his work is not going well. His sister likes to play tricks on him and makes him angry. He has companions, but he prefers a person's space. One day when her mother Stephanie suddenly returned home, she was scolded by her father as a "slut". The mother, who ran away from home from time to time, knelt and begged her family for forgiveness and promised not to leave again, but Tommy was so suspicious that his mother would stay at home. Will there be any new problems in this family?
