At the beginning of the story, Carter was just an ordinary kind-hearted bait girl who always admired an excellent and handsome boy named Tony. But Tony never remembered her name. Once, Tony went to Carter's shop to buy bait. Carter gave him a bag of bait for free on the condition that Tony would drive her to school. Tony pretends to agree to get the bait, but Carter finds that Tony's car has no places. These positions are occupied by two famous "beauties" Chelsea and Brooke in the school. Carter was ridiculed for dressing casually, but his father Mason could only send her to school in desperation.
Carter's father, Mason, is a major general special agent of the "Princess Protection Program". On the way back, I received a message to protect Rosalina, a princess from a small country named Kertaruna. Princess Rosarina is another protagonist in the story. During the rehearsal of her coronation ceremony, the evil General Kane captured Kertaruna. Therefore, Major General Mason was entrusted by the princess's mother, Sofia, to take the princess away, but Sofia himself stayed as a hostage.
After the transformation of the Princess Protection Program command center, Major General Mason took Rosarina to a rural town in Louisiana, USA. At this time, Rosarina changed her name to Rossi, and as Carter’s cousin, she was going to learn to be a normal American teenager, waiting for the right opportunity to return to her own country and defeat the power severs to inherit her throne.
When Carter was out of school, he saw his father returning home and Rossi (the princess Rosarina) who was brought back. The first day of contact between Carter and Rossi was unpleasant. Rossi did not adapt to her new identity, but instead asked Cartel to make her bed, find her pink silk pajamas, and yelled in fear when she saw the reptile. The next day, the Carters took Rossi to school together. At school, Rossi received a lot of special treatment because of his outstanding appearance. For example, when Tony saw Rosie, he didn't laugh at Rosie like he laughed at others. Instead, he gave up his seat to Rosie. When eating at noon, because Rossi didn't understand the lives of civilians, he didn't line up and received contemptuous eyes from everyone, but Tony helped Rossi out of the siege. Carter felt a little sad to see Tony being so considerate to Rossi, but she still patiently taught Rossi how to eat burgers in a civilian way. The way Rossi eats is noble. Chelsea and Brooke saw this scene, and they laughed at Rossi together. Back home, Rossi thanked Carter for her help, so she decided to help her with some chores-counting the bait, but in the process, not only did Rossi fail to count the number of bait, but overturned all the bait. In the evening, Rossi personally cooked a meal in order to express his apologies. Although Rossi was very serious and sincere, prepared a delicious dinner and wreath, but Carter was still very upset that such a person appeared to disrupt his life. Seeing Carter's reaction, Rossi was sad, so he went back to the house alone. The Carters also felt very sorry, so they followed up in the room. This time, Rossi told Carter about the situation she was facing. She said she wanted to be an ordinary American girl, because only in this way can she protect her mother's safety and save the country. Carter listened to her explanation and decided to help her be an ordinary American girl. The two reconciled in this way and went to bowling together. Although Rosie has never played bowling before, she has won a lot of shots. Coupled with her elegant temperament, she is very popular with everyone. It happened that this scene was seen by Ersi and Brook again, and Chelsea decided to punish Rossi severely. So he asked Rossi to work in his ice cream shop. In the process of this work, Rossi was ridiculed fiercely by those recruited by Chelsea. Thanks to Carter's timely appearance, Rossi was saved. Although Rossi knew he was being rectified. But she did not pursue it, because she said that the princess should be so tolerant. So, under the gaze of everyone, Rossi walked out of the ice cream shop dignifiedly. After this incident, the relationship between Rossi and Carter became very close. At the same time, Rossi also taught Carter to find his inner princess, to find the noble and beautiful heart.
The annual Homecoming Festival has begun, and Rosie and Carter have been selected as Homecoming Princesses because of their confidence and friendship. On the other hand, Chelsea accidentally discovered that Rossi was a princess secret. In order to prevent Rossi from becoming the homecoming queen, he gave Rossi a magazine. This magazine is exactly what the Princess Protection Program organization does not want Rossi to see, that is, the evil General Kane is about to marry Rossi's mother Sophia. Rossi read this magazine and felt uneasy. She wanted to return to China to save her mother and she was very determined. She said: Do you think the life of a princess is a fairy tale? No, life here is like a fairy tale. I am a princess and have the responsibility to protect my country and my people. Carter's persuasion was fruitless, so he went to see another friend of Rossi's most trust-also Rossi's designer of the king's clothing, Ai Ligan, for help. The two negotiated a plan and asked Alligan to make two evening dresses for them, one blue and the other light pink, to be worn at the homecoming prom. And, let Alligan tell General Kane that he prepared a blue evening dress for the princess. In fact, the pale pink dress is the princess's evening dress, and the blue dress is Carter's. They invited a group of girls who are usually not so beautiful to learn the manners of a princess with Rossi. On the homecoming day, Carter, Rossi and the group of girls appeared at the homecoming party with masks and noble. Tony saw Carter turning beautiful, so he threw an olive branch at her, but Carter had already discovered For the value of his own existence, he did not choose Tony. In addition, Rossi lived up to expectations and became the queen, but she found that Carter could not be found.
Rossi chased to the roof and found that Carter was about to pretend to be returning home with General Kane. At this moment, Major General Mason and the leaders of the Princess Protection Program organization appeared, rescued Rossi and Carter, and captured General Kane. Rossi and Carter hugged each other tightly, and then Rossi gave Carter his crown and told Carter that she should have the crown. At this time, Chelsea appeared. She had lost Brooke's friend and only wanted the crown, so Carter gave her the crown because Carter no longer needed it, and Chelsea needed it more than she did. At the end of the story, Princess Rosarina has also successfully become the queen of Costa Runa. And became close friends with Carter, and together they became agents of the International Princess Protection Program.
