What is the Italian film about a secret child?

A year ago on Channel Four a night, I remember an Italian film about a secret child who lives in a hole underground. The child's father is abusive to her other child and then the other child takes the mystery child, and bring food and water. I do not remember the name, but hope this information enough?

I heard of him, he said: "Lo non ho paura" aka I'm Not Scared, "and he came in 2003. Here is a good summary of it on imdb: http://www.imdb.com/title/tt0326977/usercomments
