In a small town in the 1950s a repertory company meets on Monday morning to start rehearsing the following week's play. This is a ghastly thing written by the aunt of one of the theatre's directors. The producer doesn't try to hide his annoyance about it, and is further exercised when the authoress herself arrives to help. The cast have to try and sort out real-life problems that keep intruding as they wrestle with the play's dire dialogue.
