Svante is a young boy who lives with his family in a Stockholm apartment. One day he meets Karlsson, a chubby little man in the prime of his life, who can fly using a propeller on his back and who lives in his little house on the roof.

9-year old orphan called Rasmus runs away from the orphanage. He meets a vagabond they call Paradise Oskar who likes to sing and play his accordion. Oskar makes the Rasmus world seem like a better place.

Fed up with their strict parents, Tommy and Annika run away from home, with their friend Pippi Longstocking to look after them in their long trek.
