After Elsa makes her way to Ahtohallan, the glacial river of memory, she asks the mysterious voice that she has heard throughout the film to show itself.

Elsa’s journey to Ahtohallan is in a quest for answers regarding the origins of her powers, the origin of the mysterious voice, and the truth behind why the Enchanted Forest was sealed by her fellow spirits.

In the song, Elsa sees her memories and those of her mother, Iduna. Here, Elsa discovers that the mysterious voice’s purpose was to show Elsa her destiny to assume the role of the fifth spirit—the bridge between magic and nature. Iduna also reinforces the idea that this calling has been inside Elsa all along.

Elsa is also reminded of “All is Found,” the lullaby her mother sang to her as a child.
