Tilla Morland is a major operetta star. Celebrating with friends at a fancy restaurant, she is asked to sing the hit song from her new triumph. To her outrage one of the customers gets up and leaves during her performance. A few days later the same man, an ex-army officer, turns up as her new private secretary. The two gradually warm to each other during their work, and fall in love. Each is unable to tell the other about their true feelings.
