The athletic young widow Antoinette Peterson gets into financial troubles when a business venture backfires and has to sell her car and her villa. On the road, she meets a stranger whose car she is able to repair and whom she later meets again as the buyer of her house. It is no one else than the venturer William P. Harrison to whom she lost her whole fortune in the first place. He offers her a bet: If she manages to stay for three months as his chauffeur and behaves accordingly, he would give her back her fortune. Although Harrison makes it as hard as possible for her, she keeps up. But they have already fallen in love with each other.
