Princess Anne of a certain royal family will visit major cities in Europe as the heir to the throne. The news caused a great sensation. The last stop of the European trip was Rome. Princess Anne wanted to enjoy her beautiful scenery to her heart's content, but the attendants refused on the grounds that the princess was of noble status and should not show her face in front of the common people. They injected her with sedatives. The princess pretended to be asleep. After the attendants left, she sneaked out through the window. However, not long after the visit, the sedative injected by the doctor took effect. She fell asleep vaguely on a bench beside the fountain on all sides of the square. At this time, Joe Bradley, a poor reporter from the American News Agency, happened to pass by here. He thought this was a girl who was drunk in the carnival, so he rented a taxi to take her home, but the princess slept very deeply and could not be woken up. Helplessly, Joe had to take her back to his residence. The next day, the special announcement in the newspaper made Joe realize that the girl he brought back was Princess Anne, so he was ecstatic and planned to write an exclusive report about the inside story of the princess. After waking up, the princess found the unfamiliar Joe. Joe quickly explained, and the princess felt relieved. She borrowed some money from Joe, then left him and went to wander around the streets of Rome again. Joe quickly called his photographer friend Owen, followed the princess, pretended to meet her by chance in the garden square, and volunteered to be a tour guide for the princess, riding a motorcycle to take her around Rome. At the same time, Owen also drove a car behind them and took many precious shots, and the princess was unaware of all this. The disappearance of the princess caused panic among the people, and the king secretly sent many plainclothes officers to look for the whereabouts of the princess. When Joe led the princess to the water ballroom to attend the dance, they were discovered by plainclothes police. They asked the princess to go back with them, but the princess resolutely refused. The police wanted to forcibly kidnap her back, and Joe and Owen fought with them, and the willful and naughty princess also fought and was very happy. Taking advantage of the chaos, Joe took the princess away. One day passed, and the princess finally returned to the palace, but at this time she and Joe found that they had sparked love and fell in love. However, the princess was a princess after all, and the common people were common people after all, so the two could only say goodbye reluctantly. Joe gave up the opportunity to become famous and gave the photo to the princess as a souvenir. In the affectionate gaze, the princess gently said goodbye to Joe.
