Eva i Hm

After the death of her grandfather, young Eva had shut herself off from the outside world. Worried about her mental state, her parents send her away to a summer camp near the town of Krapina, one of the most famous paleoarcheological digsites in the world, where she is promptly bullied by a boy named Marko. Whilst running away from him, she accidentally stumbles across a portal that takes her 40 000 years into the past. There she befriends a young neanderthal boy named Hm, but things soon complicate when he's attacked by a member of a Homo Sapiens tribe.
