Hanna D is an Italian take on the German movie Christiane F. It resolves around the young girl Hanna who come from an abusive home and have to turn to the street to support her mother and herself.
The movie is not a very well made one. There's actually a lot of parts in it where you just have to assume what's happened. Maybe some reels ended up missing since after all it was cult legend Bruno Mattei who edited this thing together. It also seems like they either had extremely short time to make this or just very small patience to get things right.
Even though it has it's errors if you look at how it's made it still is about the darker side of life for lost youngsters and becomes an interesting movie if you can look past it's many flaws.
The movie is also very exploitative and sleazy, so if that's not something you think you can enjoy then pass up on this movie.
