For many years, she has been working hard to make money, hoping to realize her dream with her own hands. But on the night when she was about to save enough money, she met a frog who claimed to be Prince Marvin (Naveen). He said that he was cast a spell by the shadow man and promised that as long as Tiana kissed him, he could help Tiana realize her dream. But when Tiana kissed the frog, the frog did not turn into Prince Marvin, but Tiana turned into a frog. While they were avoiding the pursuit of the bad guys, they met Louis the crocodile who liked to play jazz and Raymond the firefly. They decided to go to the mouth of the Mississippi River to find the witch mother Wattie for help. The evil shadow man sent a large number of shadow killers to catch up with the group. At the critical moment, mother Wattie appeared to save them and told them that if they wanted to become human, Marvin must kiss the real princess Charlotte. But at this time, Marvin had already fallen in love with Tiana, this persistent girl... This film incorporates a lot of New Orleans elements in both music and pictures.
