A dream island is home to a family of small rodents, the Agoutis. Untouched by humans, the community of beings are organized harmoniously along the cycle of seasons. Gouti, the eldest of the siblings, is learning about life next to his experienced grandpa. But Gouti is absent-minded. He keeps dreaming of travels, of places beyond. When an exceptional winter storm hits and devastates their island, Gouti and his family are forced to leave. A journey leading to discover other worlds, other species, and above all to self-discovery.
