I want to ask about movie I've seen years ago but I don't remember the name. It's about a boy was born during the Nazi. His father died and left him alone. And so the whole movie is about the boy's struggle for survival. I don't remember much of the detail but I remember the boy was hiding in a cave and he went to the city that had no people to search for food.

Maybe.. for those i loved.

Sorry.. it's not cave but it's something like a tunnel.

And I remember since the beginning of the movie, the boy's father was not there. And the boy ate rats and other animal he could find in the tunnel for survival.
