Brenda de Banzies runs a small public house in Wales with a wishing well. Eynon Evans is the local post man who has been trying to get Miss de Banzies to marry him for decades. Her son, Donald Houston, is engaged to be married to Petula Clark, who because he doesn't have working legs, is wracked with doubts. There's also a wealthy widow, Gladts Hay, and a young couple who aren't getting along.
It's one of those movies set in Wales where random groups start singing chorale at random moments; even Miss Clark has a rare on-screen performance. Based on a play by Evans, it hews to every stereotype about Wales you can imagine. Director Maurice Elvey opens it up with lots of vistas in the beginning. Later, when it settles down to telling its story, there are plenty of Dutch angles, none of which disguise its stage origins.
Apparently the role taken by Evans in the movie was essayed by Lupino Lane in its National Theater premiere.
