Dave and Katie Parker’s only son, Jeremy, is getting married in Australia. In spite of initial reservations, the Parkers discover that Denyse is perfect for Jeremy and that she’s the daughter they’ve always wanted. But she brings with her a colorful and largely dysfunctional Aussie family. Again Dave and Katie are fish out of water as they try to relate to a boisterous clan in a culture very different from their home in South Alabama.
After the wedding, Denyse feels heartbroken that her younger brother, Trevor, did not attend. Details emerge that lead Denyse to believe her brother may be in trouble. Impressed by his parents’ sleuthing experience in Minnesota, Jeremy volunteers them to locate Trevor. Their search leads them on an adventure through Australia and New Zealand.
Unfortunately, others are also searching for Trevor, with far more sinister intentions. With a talent for irresponsible chicanery inherited from his family, Trevor has left a trail of trouble in his wake and has been forced into servitude. Can Dave and Katie locate him in time?
