Because of her mother's career, Ida had to move to another town and become the "new girl" at Winterstein School. She had a hard time in her new class: Ida, who couldn't make friends, had to stay next to the shy, introverted Benny. One day, Ida's teacher introduced the children to Mortimer Morrison, a man who traveled the world in search of "magical animals". Every animal is destined to be the soul mate of a child. Of all the people, Ida and Benny, the transfer students, were the first to have magic partners in the class! From now on, Benny has an old and clever sea turtle, and Ida has a cunning fox. When things continue to disappear in the school, there are super thieves in the school. Children and magical animals solve the mystery of super thieves in order to help their friends wash away their suspicions.
