Polly Purebred is caught in a whirlwind—at work, she has a new boss giving her orders; her boss's secretary is so pretty it's driving her mad; Taptap won't stop visiting her; and worst of all, feelings for her roommate are starting to surface. With so much turning her life upside down all at once, she never stops to consider why her boss decided now was the time to take control.

After being hounded by Underdog, Taptap receives mortifying news—he, one of Biggers's most wanted criminals, is the long-lost brother of Biggers's greatest hero. But he refuses to believe this, and becomes determined to prove Underdog wrong. Unfortunately, he finds nothing... and he is left to—somehow—accept these tremendous changes in his life. And what about when Riff finds out?
