:) please can any help

I saw a great film years ago and have been looking for it ever since.

It was set in a male prison. A female dentist comes in to treat the inmates and falls in love with one. Then goes on to help his appeal. He was in because he killed his wife but says he returned home to find her already dead. He is eventually set free. There is a very passionate scene in a toilet.


I thought the main star was Tim Roth, but cannot find a like film in his listings.

Here's one with a prison Dentist and Roth. Might be it?
