Many animals live in King Magus's ghostly garden, but they are not standard zoo creatures: they were all once people. The cruel ruler has enchanted them, as he did to Hanna, who refused to marry him.

When the young shepherd Elias goes to the castle to rescue his beloved Hanna, he discovers that the King's magic powers come from a mysterious mirror. The only thing that can save Hanna is water from the moon sea, but the journey there is brimming with danger.
