Die Hölle in der Stadt

Nella città l'inferno (Behind Closed Shutters) is a 1959 Italian film directed by Renato Castellani.

When the wide-eyed Lina (Giulietta Masina) lands in a women's prison, she meets a world-weary prostitute named Egle (Anna Magnani) who looks out for her. After Egle teaches Lina what she knows and begins to harden the girl, Lina commits another crime on the outside and winds up back in jail, a shell of her former self. Egle, meanwhile, who had taken a genuine liking to Lina, has tried to better herself and is shocked to see what has become of her former protégé.
