Tom traces his American ancestry to Charles and Rebecca Chadwick, who came to England and had three children--Victoria, Brian, and Tom's great-grandfather Harry. Tom, Bea, Keith, and Keith's Moldovan wife Luba head to a farm in Derbyshire to meet Tom's great-uncle's son Graham, his boy Ronnie, and Ronnie's wife Emma, who explain why their strand of the family are redheads. Graham and Keith instantly bond over their shared delight in the sitcom 'Move Along Please,' but Tom is perturbed by Ronnie's odd sense of humor, such as pretending to castrate a lamb. He is relieved to get a call from Al, his cousin in California with whom he had left an answer-phone message; Al invites Tom to stay with him and his wife Kitty. Meanwhile, zookeeper Pete must mate two alpacas, an exercise that leaves him feeling broody.
