Piujuq is a kind young woman who loves to take long walks on the tundra and dance by her favourite lake surrounded by butterflies. But one day, she encounters a stranger on her walk. When this person asks a favour of Piujuq, she happily obliges, and that kindness leaves Piujuq stuck in the body of a caterpillar. Alone, and thinking that no one could ever love her because of how she looks, Piujuq does not return to her camp. Instead, she lives a lonely life on the tundra. Until one day when another stranger appears.
