Johnny Jones is an action reporter on a New York newspaper. The editor appoints him European correspondent because he is fed up with the dry, reports he currently gets. Jones' first assignment is to get the inside story on a secret treaty agreed between two European countries by the famous diplomat, Mr. Van Meer. However things don't go to plan and Jones enlists the help of a young woman to help track down a group of spies.

The battle of the sexes as drawing room social satire. Philippe, a middle-aged newspaper editor, has lived for six years with Paulette, a successful stage actress. He tells her friend Claudine, a realistic and enterprising reporter, that he's thinking of proposing. Into the mix steps Carl Erickson, a charming Hollywood matinée idol in Paris briefly. He meets Paulette, sees her act (his box seat compliments of Philippe), and sets out to seduce her. The next two days bring talk, tears, separation, despair, surprises, and, perhaps, reconciliation as characters speak "exactly half the truth." It's a quadrille of changing partners.
