Porridge Christmas special No Way Out

British TV Prison Sitcom . Classic stuff from Ronnie Barker! This is the Christmas Special (one of two, made, the other being "The desperate Hours"). Fletcher fancies a holiday - a twofold solution to the retribution of the "screws", finding out about "Tommy Slocombe's escape tunnel(!)" Can he connive a stint in the prison hospital, as a "near as you'll get" solution, as a "holiday" in Slade prison, using a n old injury!??!
