One warm summer night, a shower of shooting stars sweeps across the sky. Elinor looks out of her window and makes a wish: 'Make grandpa well.' Elinor waits and waits for her wish to come true. Then, one morning, she receives a postcard from a shooting star! Instead of granting her wish, however, the star tells her not to wait for miracles from shooting stars anymore. Outraged, Elinor sets out to change the shooting star's minds, embarking on an adventure that leads her to the far reaches of outer space. Can she convince the stars that granting wishes is their most important job of all?
