About 12,000 years ago, at the dawn of civilization, a small Neanderthal tribe struggles to survive the harsh conditions of the Ice Age. Among them is a young man named Gato who shows exceptional skill in hunting and tracking. His prowess earns him respect from his peers, but Gato longs for something more than the daily fight for survival. Meanwhile, a young female named Nara demonstrates a unique talent for crafting and creativity. Her innovative spirit sets her apart, and she dreams of exploring life beyond the confines of the tribe. As the tribe faces dwindling resources and increasing threats from the encroaching cold, Gato and Nara's paths begin to intertwine.
