Turn the Key Softly (1953)
I had my doubts but gave it 20 minutes and glad I did as it turned out to be a really good film.
Three women are released from prison at the same time and go their separate ways with a promise to meet again and of course it was inevitable the meeting would see them again at the prison gate going back in, but did they................
Ravishing Joan Collins playing a prostitute determined to turn over a new leaf by marrying solid reliable Glyn Houston who is a bus driver and not very glam. Joan succumbs to her passion for jewellery and some of her old mates from the streets tempt her into the old life.
Sophisticated Yvonne Mitchell also wants to start again and after a couple of false starts finally gets a job in an office, but her old boyfriend/louse cat burglar (Terence Morgan) who got her into trouble when she was caught and he wasn't, fools her into one last big job robbing a theatre.
And finally, old dear Kathleen Harrison who is an inveterate shop lifter and is shunned by her family and her only companion is a dog called Johnny, so you know it's going to end requiring handkerchiefs.
Good sub-plots, unexpected end and I can highly recommend it, with appearances also of Geoffrey Keen and Thora Hird.
