For better, for worse (1954)

In postwar London a young graduate and his girlfriend decide to marry. Her well-to-do parents are not convinced, but they agree once he has got a £5.10.0 job and a 30/- a week single-room flat. The newly-weds find money fearfully tight, the flat cramped, the neighbours a trial, and her parents always hovering. Can faith conquer all? Is there some way of getting rid of tea-leaves except down the sink?
