Percy (Lucy Baotong Lucy Boynton), Pauline (Emma Watson Emma Watson) and Petrova (Yasmin Paige Yasmin Paige) are three lonely orphans. Fortunately, they meet the explorer Gem (Richard Graves Richard Griffiths) and become his adopted daughter. In spite of his eccentric personality, Graham, who is kind by nature, gives the children the warmth of his family. Despite her miserable childhood, the three girls still kept their dreams. Petrova wanted to be a pilot, Pauline was full of longing for the stage in the spotlight, and Percy devoted a lot of time and enthusiasm to ballet. The sudden disappearance of Gem put the lives of the three girls in trouble, and financial constraints meant that they would never be able to reach their dreams again. At another critical moment, the kind-hearted people selflessly lend a helping hand. With their help, the three girls not only tide over the difficulties, but also have a deeper understanding and understanding of life.
