Bea and Monk audition to perform at a children's birthday, while Tom starts digging deeper into the life of his grandfather William, who he suspects might have competed in the 1948 London "Austerity Games," a far cry from those of 2012. After learning more about the games from Mr. Pfister, Tom visits his great-aunt Victoria's friend Mildred, who is able to shed some light on William's former athletic prowess, and on why Victoria left Tom the chest of family curios. 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. While at the gym, Pete bravely accepts a challenge from a much younger timer. Bea and Monk perform their first professional gig at a wedding reception.
When Mr. Pfister discovers an unforeseen aspect of Tom's great-grandfather Harry's life, it leads Tom and Pete to the south coast of England, where Harry died many years before. They meet Sybil, an impossibly old woman who still lives next door to the house Harry lived in and remembers him from her childhood. 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 and Mitch, the two friendly gentlemen who run the theatre. It also inspires Tom and Pete to engage in a unique competition, but not before Pete has set Tom up on another extraordinary date.
