The point that I should start is the official title, "The girl in the cage", I prefer by far the worldwide title since it focus more on the protagonist (has an off-topic: the Italian title makes it sound like a documentary). If you like the old drama/mystery/crime movies like I do, you will love this one, doesn't add really nothing to the gender, but it's so well produced and the acting was on point, got to love when you see an actor, Nikolaj L. Kaas in this case, waking up in a realistic way, the mood of the whole movie brings you to that slow passing detective drama, rare in our days, with all the CSI around, and ends up with a very thrilling ending.
