Shep wins by a landslide. A lover of democracy and dog treats, Shep is rapidly earning the goodwill of Fossett's citizens. Tourists are streaming in and everyone wants to glad-paw the new mayor. Suddenly Melanie and Shep are media darlings, with requests for interviews, game shows, and personal appearances through the roof. But there's trouble in paradise. Determined to win back his former wife, Bryce MacDonald discovers a rival in tabloid reporter Chad Cameron, who's in Fossett to dig up dirt on Melanie and Shep. He finds a willing co-conspirator in the malcontent who lost the election. Hounded by the press and desperate to head off a potential dog-napping, Melanie unwittingly puts herself in danger. Shep comes to the rescue, proving his mettle to save his faithful human at the risk of his own life . . . and new political career.
