British playwright Frederick Lonsdale had many of his drawing room comedies transferred to the screen, and this is one of his best. Ralph Forbes is in love with Ruth Chatterton, a British star actress, and forces the issue of marriage by announcing their engagement in the newspapers. He is the son of staid Lord Crayle (Herbert Bunston), who gathers the family together at his estate to try to determine what to do about it. They consider offering her a sum of £5000 to deny it when Forbes brings her to the meeting. Except for Basil Rathbone, the family is dead set against the marriage and think Chatterton too low in society. In a funny twist, her father, Robert Bolder, arrives to object to the marriage too. He thinks Chatterton is a genius at providing entertainment for the masses, and doesn't want her marrying beneath her station. He suggests they approve the engagement providing the marriage is delayed for six months, by which time Forbes should be totally bored with her. They agree and so does Forbes and Chatterton. She stays at the estate and brings about a transformation in the most reserved members. It was fun to watch Herbert Bunston do a solo modern dance to the tune of "Lulu Comes Home." And Frederick Kerr, who normally doesn't drink, gets drunk as he extols the virtues of the "gulley washers" Chatterton introduces him to. Meanwhile, Rathbone and Chatterton fall in love, but she is also aware he has been carrying on a long-term affair with a married Parisian woman, who he had said earlier he would marry if he could. He promises to give up the woman, but things change as they hear on the radio that the husband of that woman has died. Now Chatterton feels that woman will always be between them, but Rathbone is adamant about giving her up. Chatterton puts through a call to her in Paris and hands the phone to Rathbone, who has some difficulty going through with his plan. And Forbes has some ideas about his life, too.
