King Valemon becomes the ruler after his father's death, but a vengeful witch transforms him into a polar bear as she desires to be his queen. Valemon must find a bride within the seven years he will remain a polar bear, so he journeys to Winterland and marries. Despite their happiness, his wife is forbidden from seeing his face when he turns back into a human at night. If she violates this rule, Valemon will be permanently bound to the witch.
