Rosie & Moussa is a movie, based on the children books 'Rosie en Moussa' from Michael De Cock and Judith Vanistendael. Rosie and her mom move to the other side of town. In her new apartment building, Rosie meets Moussa. Together, the two of them wander off to the roof, even though it’s strictly forbidden. On the rooftop, Moussa promises Rosie he will go with her when she visits her dad, who is in prison. Rosie wants nothing more than to bring her mom and dad back together, but will she succeed? Because mom doesn’t want anything more to do with dad... and to make matters worse, she falls in love with another man.
