Sparks fly as Magnani plays opposite another legend of Italian cinema—Giulietta Masina—in this explosive women-in-prison drama. Masina is the naïve young innocent wrongly convicted, Magnani the volatile hardened convict who corrupts her. Despite its title, the film is less an exploitation shocker than a gripping character study, with the interplay between Magnani’s livewire intensity and Masina’s gentle guilelessness generating real dramatic tension. Each woman gets ample opportunity to shine, but the best moment belongs to the electrifying Magnani. The sight of her shimmying down a cellblock while shouting “rock and roll!” is worth the price of admission alone. 35mm print from Istituto Luce Cinecittà.
