But when the blonde Kelly gets in his cab, he is caught unawares by her provocative and unpredictable attitude, also because she has a disarming quality. He has to do his very best to keep his distance. Their whole conversation takes place inside the cab, with many close-ups of their faces, while the street lights flash across the windscreen and the city glides by almost invisibly.
