Women-In-Prison movies at their best can be either serious or fun, but this terrible film is neither. It is....nothing. It just sits there, never doing anything exciting. Incompetence and cheapness are obvious in almost every frame - the climactic prison "riot" is represented by a couple of off-screen shotgun shots. It's really unerotic too - as I've said before, explicitness (which is certainly present here) does NOT equal eroticism if there is no proper buildup. The heroine spends the entire movie seeking "the truth" about her sister's death - a truth the viewer knows right from the start. Simply put, this film is an endurance test for even the most die-hard WIP fanatics. (*)
