Major Sinclair Yeates, an Englishman, arrives in a rural area of Victorian Ireland. He has married his colonel's daughter and has decided to take up a new career as a Resident Magistrate. Major Yeates quickly meets the hard-riding Knox clan, including Great Uncle McCarthy and young Flurry Knox, his landlord.
Flurry has challenged a visiting Indian polo team to a match and sold an incorrigible young filly to John Cullinane. The Maharajah and his team are vastly better than the Skebawn team, and the whole game goes a bit pear-shaped when John Cullinane's filly goes nuts, topples a goal post, and disappears with a horde of spectators in tow.
Babs fondly reminisces about her old friend, Julian Chichester, who is coming to stay at Shreelane. But no sooner does Chichester arrive than he begins to scorn the Major's household, including a beloved canine. Flurry decides to teach Chichester a lesson or two with the canine as an unwitting accomplice.
