The Hedenhös family lives in the Stone Age. They are a warm family that is always together, solves everything together and likes to hug. Then they see a bright shining star in the night sky and they get the idea to organize a party "for the star". But then the star goes out and forms a black hole. The family then decides to go and light the star using a tree rocket. They make the rocket fly with the help of "fairy grits". They reach the black hole, but fail to ignite the star and instead get stuck there.
