Later, Sonya was given to Ben Cohen as severance pay by her master. Ben Cohen's frustration was fully seen by his daughter Kyle (Dakota Finney). In order to help her father and Sonya regain their confidence, she made a detailed plan. first, she persuaded Ben Cohen to take good care of Sonya with her. when Sonya got back on her feet little by little, she tried to get Ben Cohen to take on the seemingly impossible task of winning the Horse Breeders Cup Classic.
