Having harnessed her ever-growing power after lifting the dreadful curse of eternal winter in Frozen (2013), Queen Elsa, the grand conjurer of snow and ice, and her sister, Princess Anna, now enjoy a happy life in the peaceful kingdom of Arendelle. However, a melodious, insistent voice only Elsa can hear keeps her awake, inviting the Snow Queen to a fabled mystical forest. As a result, unable to block the thrilling call of the secret siren, Elsa follows the voice into the perpetually misty realm in the woods to find answers. But, more and more, an inexplicable imbalance hurts her kingdom and the neighboring tribe of Northuldra. Is Queen Elsa's legendary magic enough to restore peace and stability?
Anna, Elsa, Kristoff, Olaf and Sven leave Arendelle to travel to an ancient, autumn-bound forest of an enchanted land. They set out to find the origin of Elsa's powers in order to save their kingdom.
