Is it INNOCENT SINNERS?
You got it! Good job, Arturo. This film was shown on TCM during the wee hours of the morning several weeks ago. (Or was it several months ago? I don't remember.) It doesn't seem like much on paper, but it really is a good film. I didn't expect to enjoy it as much as I did. I was particularly impressed by the young lead actress (June Archer). If anyone is interested in seeing this film, you can find a copy of it on Youtube. Do a search for "Innocent Sinners 1958".
Your turn, Arturo.
