Three years ago, the purebreds and mixbreeds lived in peace and perfect harmony. Every canine befriended one another, even considering each other family if not by blood. However, a German Shepherd and Doberman mixbreed had been accumulating a devious plan for total authority with his mixbreed comrades. One night, the leader of the purebreds was with his daughter for her to retrieve a lost material. He was knocked to his side, out within a second's time as he caught a glimpse of his daughter being captured. He swore for vengeance against the family whom betrayed him, and now his one and only goal is to win his daughter back from the clutches of the mixbreeds.
