Mia, an 11-year-old girl who lives on an African farm with her family, has been unable to integrate into local life in South Africa since she came from London. Until the farm gave birth to a rare little white lion Charlie, the little white lion accompanied the lonely Mia out of the haze and brought her a lot of joy. As Mia and the white lion grew up, the adult white lion became uncontrollable and the family had to isolate it. But gradually, Mia realized that there was a hidden conspiracy behind it. In order to let the white lion live freely, Mia decided to take the white lion on her way home and embarked on a wonderful adventure.
