Cage Without a Key

I just now "found" this film after looking for it for years. For some reason, it made a great impression on me, even though I wouldn't call myself a huge Susan Dey fan. I was surprised to see that it was made so long ago, which makes me wonder whether I saw it on a re-run. Anyway, the characters were fairly well drawn -- maybe they are stock/cliché characters that I'm simply too naive to recognize as such, not being a devotee of women-in-prison films -- but I recall the basic plot, characters and even some of the dialogue, even now. I thought there was a good ethnic mix, which strikes me as fairly forward-thinking for that time period, especially. And I liked that the squeaky-clean-imaged actress of Partridge Family fame would end up in a picture like this, albeit as the stereotypical "good girl" who doesn't truly deserve to be there.
