Every morning, Lis puts the things she likes the most in her backpack. There are the bowling pins and the scooter for Sofi, Rudy and Cata to play. But Lis begins to realize that her three friends do not treat her with the same affection: they do not let her play secret games and they even steal her lunch!
Day after day, Lis will see how that backpack she carries gets bigger and bigger. And is it that there are feelings that weigh heavily, such as sadness, shame or fear of explaining what is happening to you?
Will he find a way to empty all that weight?
