Prigione di Donne, or Riot in a Women's Prison, is a 1974 Italian exploitation film directed by Brunello Rondi, famed for his writing collaborations with Fellini. This entry into the women-in-prison (WIP) genre of the 1970s has its moments of trashy fun but ultimately fails to excite, with a tedious pace and underwhelming story.

The film begins with a peaceful group of hippies, including our main character, being arrested by fascists. Guilty by association, she finds herself in a pre-trial jail run by nuns, a seemingly odd but intriguing concept that sets the tone for the rest of the film.

The first half of the movie is a slow burn, taking its time to build up to the eventual riot suggested by the title. Along the way, we're treated to some choice scenes of sleaze and nudity, catfights, and over-the-top moments that fans of the genre will appreciate. However, these moments are few and far between, and the wait may deter all but the most dedicated fans of exploitation cinema.

The story is unengaging, and the acting leaves much to be desired. The film attempts to critique the state oppression and the unjust imprisonment of the women, but this intelligent parable is let down by lackluster performances and a general lack of energy. The much-anticipated riot scene, a fight between guards and prisoners, falls flat and is even embarrassing at times.

Where the film does find some success is in its atmosphere and setting. Rondi and cinematographer Gino Santini create a seedy, oppressive world that feels authentically 70s. The prison setting is effectively utilized, and the nuns add an interesting dynamic, subtly exerting a form of moral and physical control over their charges.

Overall, Prigione di Donne is a passable entry into the WIP genre. While it has some enjoyable moments and a unique setting, it is ultimately let down by its slow pace and forgettable story and performances. Only recommended for die-hard fans of exploitation cinema or those with a particular interest in the era's Italian filmmaking.
