Tiana is a girl who never believes in fairy tales. With a gift for cooking, her biggest goal is to open her own restaurant. She has been trying to make money for many years, hoping to have enough hands to make her dream come true. But on the night when she was about to save enough money, she met a frog who called himself Prince Naveen. He said he was enchanted 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 become Prince Marvin, but Tiana became a frog. While avoiding the bad guys, they met the jazz-playing crocodile Louis and the firefly Raymond, and they decided to go to the mouth of the Mississippi River to ask the witch mother Watti for help. The evil shadow men sent a large number of shadow killers to catch up with this group, and at a critical juncture, their mother Woody appeared to save them and told them that if Marvin was to become human, Marvin had to kiss the real princess Charlotte. But at this time, Marvin had already fallen in love with this persistent girl in the process of getting along with Tiana. This film integrates a large number of New Orleans elements from both music and picture, creating for the film.
