High school seniors In-hye, Seo-hee, Jeong-ae, and Soo-min are at a crossroads, turning in blank papers for their "thoughts on the future" assignment. Their true focus is a small animal enclosure at their school. When the school decides to tear down the habitat, the four girls devise a plan to relocate the ducks, rabbits, and chickens to a secret campsite in the mountains. The film follows their journey as they attempt to build their own "utopia" in nature, capturing the anxieties, friendships, and small adventures of youth as the seasons shift from summer to fall.
