1950 / 60s BRITISH JAIL ESCAPE FILM?

[Clancy]

I saw it in 1960s I think. Escape entrance was under / in the jail's plant 'hot house' / 'green house' where they grew various flowers and plants . I think it was a criminal jail rather than a war jail, but I might be wrong. Memory is that at the end of the movie, the tunnel hole comes up in grass outside the wall and the man escapes.

Any suggestions would be appreciated.

Sounds like "Two Way Stretch" .
