Nightingales

This series dealt with a group of female student nurses under the care of Susan Pleshette(from The Bob Newhart show fame). Young student nurses who spent quite a bit of time out of their uniforms.

If this sounds like Roger Corman movie "Night Call Nurses", you would be correct(except for the part of it taking place at a psychiatric hospital.

If this sounds like the current hit TV show Grey's Anatomy, you would also be correct.

This show was canceled before the first season was complete due criticism of the overt sexual nature of the show. I thought it fairly good and I have yet to see Susan Pleshette in anything since.
