He finds an old black-and-white photo in the chest that his father, Keith (Michael McKean), believes is Tom's great-grandfather, Harry. With the help of Mr. Pfister (Jim Piddock), his avuncular neighbor, and Pete (Tom Bennett), an old school friend, Tom tracks down Neville St. Aubrey (Christopher Fairbank), a strange expert in the field of antique photos, who discovers intriguing and revealing information about Tom's ancestor.

Their investigation takes them to a regional theatre, where he and Pete learn more than they ever wanted to know about Harry's life and loves from Rex (Hugh Sachs) and Mitch (Guy Siner), the two friendly gentlemen who run the theatre.

With Keith's help, Tom and Pete visit the gym where Tom's grandfather William trained for the Games, and meet some old-timers who actually knew him.

Tom finally has an interview for a job. He also discovers he has cousins in both Derbyshire and California, and makes a plan to visit and learn more about the Derbyshire branch of the family tree. Meanwhile, Pete has to perform a delicate "procedure" on an alpaca at the zoo. Tom, Bea, Keith, Luba (Lisa Palfrey) and Monk drive up to the Derbyshire farm owned by their cousins from the North. Tom is interested to find out if the grass is really greener in the country, and equally determined to get to the bottom of a dark family secret. Culture Clashes notwithstanding, Tom gets his answers and some family truths are finally revealed. The family-tree plot thickens as he also hears from his American cousin, Al (Ed Begley, Jr.), on the trip. Pete's life-affirming mission at the zoo proves to be a no less sticky venture.
