A little bit of an underrated gem here. Playboy gets thrown in prison because he was in the car 4 thieves were in when they were caught. While trying to beat this rap, Playboy Brady toughens up and gains friends, the wrong ones. People, including the new warden want him to be a good prisoner example! This goes along in a great pace. The one problem I have is that this should have ended when it had one, but then it kept going and seemed to fizzle out with a fuzzy wuzzy ending because Everyone Has A Heart. But still worth a watch.

Reckless socialite Gray gets framed by a gang of toughs in a rather implausible way. He gets sent to prison (With ear-achingly strident music). Since no one believes his (true) story he turns mean under the evil warden. The evil warden gets axed and a former guard gets appointed to the post. He then tries to become more friendly to the inmates, but Gray and his cellmate block him! Can he reform Gray?

Why do they have to take a pretty good movie and ruin it in the end? It's as if they get together and say, Ya know..this flick was to good so whaddaya say we throw in some garbage right in the end so everyone will leave the cinema feeling ripped off?
Sure it was a bit pie in the sky all the way through, but still pretty good, but the ending with the thug whimpering like, gee fellas.. whaddaya say we blow this joint and kill the copper just for dramatic effect? No? Well gee you guys are no fun..

But you can blame this movie for a lot of evils in the film industry.
