In the middle of the mountain wilderness of the Alps, a glowing meteorite strikes a glacier and brings a Neanderthal boy frozen in ice back to life. This boy, Bataa, meets Sophie, a girl who has run away from a vacation cabin in the mountains. At first, the two seem separated by language and time, but they quickly discover they have things in common: Sophie has lost her mother and cannot find her place in her new blended family, and Bataa also feels abandoned and longs for his family.
