Willie Mossop (John Mills) is a gifted but unappreciated bootmaker employed by the tyrannical Henry Horatio Hobson (Charles Laughton) in his moderately upmarket shop in 1880s Salford, Greater Manchester in Lancashire. Hard-drinking widower Hobson has three daughters. Maggie (Brenda De Banzie) and her younger sisters Alice (Daphne Anderson) and Vicky (Prunella Scales) have worked in their father's establishment without wages and are eager to be married and free of the shop. Alice has been seeing Albert Prosser (Richard Wattis), a young up-and-coming solicitor, while Vicky prefers Freddy Beenstock (Derek Blomfield), the son of a respectable corn merchant. Hobson does not object to losing Alice and Vicky, but Maggie is far too useful to part with. To his friends, he mocks the plain, severe Maggie as a spinster "a bit on the ripe side" at 30 years of age.
