Despite the initial set-up (2 American girls in a foreign - here African - country get arrested and sentenced to 11 years in jail for a crime they didn't commit), "Purgatory" is not really a Women-In-Prison film. It almost completely ignores the daily prison life of the women and focuses on one aspect only: their sexual exploitation. The warden has set up a prostitution ring and the prisoners are used to satisfy the needs of many high-paying customers. After 75 minutes of this repellent junk, we finally get to the escape part. "Purgatory" supposedly has serious intentions: there are even title cards telling us what date it is, and at the end another card telling us what happened to the surviving characters, as if this was based on a true story, even though at the end of the credits there is the usual "any similarity to real persons, living or dead, is purely coincidental" disclaimer. But it is technically rough, even amateurish at times, and although Tanya Roberts deserves credit for taking on a role that has her appear completely unglamorous, she's still too limited an actress to carry a movie by herself.
