The flock of sparrows, including Willy, flew across the city to the barn where they used to live, unaware that they were being trailed by a dog and Sissy, who was following them to the barn. Once in the barn, Willy catches sight of a mouse waking up Blackie and alerts him about the sparrows in the barn. Blackie attacks the sparrows and nearly eats one named Amy. Not abandoning his new friend, Willy drops a light bulb on Blackie's head, distracting him long enough for Amy to escape unharmed. Willy then escapes the barn, and Sissy appears and becomes acquainted with Blackie since they both share a taste for sparrows, and want to eat Willy.
