In Paris, Madeleine de Beaupre cons jeweler Aristide Duvalle and psychiatrist Maurice Pauquet by telling each man that she is married to the other. Duvalle delivers a string of pearls worth millions of francs to Pauquet's office, expecting to be paid, but Pauquet thinks he is a new patient who has delusions of needing to collect debts. Madeleine is there to introduce them to each other, and departs with the pearls before they figure out what she has done. While driving to the Spanish border, Madeleine splashes mud onto Tom Bradley, an American automotive engineer vacationing in Europe. Then as they approach the border, her car's horn control sticks "on", to the annoyance of the customs officers. Tom fixes it and they go into the office together. Luggage and purses are being inspected, so she decides to hide the pearls in his jacket pocket. On the road, she pulls ahead of Tom, then disables her own car so that he will have to give her a lift. But he has changed jackets. She says she is going to San Sebastián, and he offers to drive her there. En route she seizes an opportunity to steal his car, leaving him standing in the road—along with the suitcase his other jacket is in. She then crashes the car while evading police. They make their way separately to San Sebastián. There "Countess" de Beaupre meets her accomplice, supposedly her uncle, "Prince" Carlos Margoli. Tom locates Madeleine with the help of a policeman, who cannot imagine that a charming countess would steal a car and does not even stay to see if Tom identifies her as the thief. As it seems that Tom still has the pearls but does not know it, Carlos quickly offers to pay for the car, and Madeleine pretends to be attracted to him. They all become friendly and go together to stay at Carlos's villa. There, when Tom wears his other jacket, Carlos gets the pearls from him using another trick. Carlos now wants Madeleine to accompany him to Madrid to sell them, but she has actually fallen in love with Tom, and wants to leave the gang instead. Despite the attempts of Carlos and "Aunt" Olga, another gang member, to break them up, they become engaged. After Carlos and Olga taunt Madeleine about being unable to tell Tom the truth about herself, she throws caution to the wind and does just that. They steal the necklace back from Carlos and return to Paris, where Madeleine returns it to Duvalle. He personally forgives her, but says she must still face the authorities. The final scene is Tom and Madeleine's wedding, where her parole document is accidentally shown, proving that she has done so. Pauquet and Duvalle, who now is his patient, attend the wedding as witnesses.
