Down on his luck in love and life, having recently lost his job and girlfriend, 30-year-old Tom Chadwick has an unsure sense of his own identity. But when he inherits a mysterious box, Tom starts investigating his lineage and uncovers a world of unusual stories and characters, acquiring a growing sense of who he and his entire family are. On their last day in California, Bea, Monk and Pete hit the beach, while Tom, accompanied by Ally, meets Toms distant cousin Melvin Schmelff, whose grandfather was Tumbleweed Tim, a famous silent-movie cowboy star. Tom, Bea, and Pete drive to Barstow, where they find that great-great-grandmother Rebecca was not Native American, as Tom had thought. Tom stands up for himself, observes California wildlife and looks for civility amidst civil war. Tom arrives in Los Angeles to stay with his American cousins Al and Kitty Chadwick as he tries to discover more about his great-great-grandfather. Tom discovers he has family in both Derbyshire and California, and plans to make a visit and learn more about the Derbyshire branch of the family tree.
