Edward has gone to Los Angeles on business. One afternoon, when he was ready to go back to the hotel early, but his limousine was stuck, he borrowed an advanced Lotus coupe from his friend lawyer Philip and wanted to drive back to the hotel by himself, but he got lost and drove to the red light district unconsciously. At a red light intersection, Edward stopped at the side of the road and kept trying to shift gears because he was not familiar with the operation of Philip sports car. At this moment, a beautiful young prostitute, Vivian (julia roberts), mistook Edward, who was lost here, as a client. Encouraged by her good friend Kate (laura san giacomo), she stepped forward to talk to Edward. Kate is a cocaine addict. She took the money Vivian should pay the rent. Under the pressure of rent, Vivian took the initiative to get on the bus after Edward asked for directions. She followed Edward to the hotel. Edward thought Vivian was special, so he continued to "hire" her for another night.

Edward talks about buying a shipping company. Philip wishes he could bring his date. Edward decided to spend 3000 yuan to hire Vivian for a week as a date for social activities. Vivian accepted Edward's request and began to get along with each other for a week. During the week Vivian and Edward were together, Vivian changed a lot from appearance to heart. With the help of the hotel manager, she put on an evening dress and learned the basic etiquette of eating. She accompanied Edward to various banquets and met many decent people. The two gradually fell in love with each other and could never leave each other again.

When Edward's lawyer Philip heard that Vivian was a prostitute, he insulted her with words and even tried to hit her. Edward hit him. In spite of this, Edward still failed to make concessions to their respective identities, and could only give Vivian full material support and reluctantly gave up this relationship. Seven days, although it was a day built with money, Vivian didn't take the stack of money that was very important to her, because what she wanted was far more important than money.

A week passed quickly, and Edward wanted to pay her to live in an apartment in new york, but Vivian simply refused. Vivian left Edward and went back to her apartment. She decided to go to school and start a new life. Just as she was about to go out, Edward's car was parked outside, and Edward saved Princess Vivian like a knight.
