Irene Vail (Jean Arthur) tente de divorcer de son époux, un milliardaire à la jalousie maladive. Pour la récupérer, il paye son chauffeur pour compromettre son épouse dans sa chambre d'hôtel. Mais, Paul (Charles Boyer), qui est dans la chambre voisine surprend les éclats de voix d'Irene. Il intervient en se faisant passer pour un voleur de bijoux; puis emmène Irene, effrayée, dans un taxi.
Paul: Do you mind, if I do?
Paul: Oh! I'm sorry. The clasp is bent.
Irene: But, why?
Paul: Don't you want them?
Irene: But, you're a thief!
Paul: I beg your pardon!
Irene: Oh, I'm so sorry…
Paul: I was in the room next door. I was putting a friend of mine to bed who had a little too much to drink. I couldn't help but become very much interested in that unusual little scene you were playing.
Paul: The reason I kidnapped you was to return your jewels.
Irene: Oh! But why did you take them?
Paul: If I didn't make believe I was a thief, my presence would have compromised you, I think, as much as your chauffeur's.
Irene: Oh! I'm awfully sorry!
Paul: I forgive you.
Irene: Where are you taking me?
Paul: I would think you'd like to do a little thinking before you go back. We are just riding around.
Irene: Oh! All I seem to say is oh! Yes, I must think. Did you say something about a cigarette?
Irene: Thank you! Yes, I must think.
