Rosie and Mama moved to the high-rise across town. I bet it's gonna be a long time before Rosie makes a friend here. Wrong! The neighbour's boy Moussa persuades her to go up to the roof of the house, which is strictly forbidden. But it's beautiful, because you can see the whole town from there and all the way to the sea. But the two of them are locked out by mistake and no one suspects where they are. But Rosie knows from her mother that there's always a solution for everything.
