Up high, in the dark, dark sky… a message: LOST, ONE SMALL STAR.
When a little boy stumbles across a special star, he puts it in a jar and takes it on adventures. Together with his big sister, he takes his special treasure with him everywhere – to the cinema, to the swimming pool and even to the toilet! But the poor star is sad and misses its home. Can the little boy and his big sister find a way to send the star safely back?
