While this is NOT a screener, it comes in a smaller cardboard envelope that holds the disk not a full DVD case. Can be easily transferred to a DVD case you may have at home if you so desired.
Wrath of the Crows is a 2013 Italian psychological horror film directed by Ivan Zuccon.
The film takes place in a squalid, narrow, and vaguely fascist-looking prison, where inmates are forced to suffer injustices from the guards and their unseen superior, "The Judge". The prisoners know the rules but have no memory of their past lives, only the evil they committed to land them there. 
The plot centers on a mysterious new prisoner, a beautiful woman named Princess who arrives covered only in a coat of raven feathers. Her presence causes a stir among the inmates and guards, inciting curiosity, envy, and sexual tension. Soon, Princess reveals a dark and supernatural nature, possessing telekinetic powers and otherworldly strength that begins to turn the tables on her captors. The film is described as a brutal, gory, and atmospheric horror/mystery with a final twist.
