During a convent picnic, Raffles, a dog, runs off with a purse. His master, the Gypsy, is hauled to jail. Raffles joins the picnic and coaxes shy little Jamie into the games. No pets are allowed at San Tanco, but Sister Bertrille lets Raffles follow them home. Mother Superior makes a temporary exception when she sees Raffles winning over Jamie. The dog, trained to fetch, retrieves a ball, and another purse. Jamie and Sister Bertrille can't reform Raffles. Sister Bertrille and Sister Jacqueline set out to return Raffles' big haul -- six purses. The car gets a flat tire and they panic at Officer Peralta's approach. Later, he can't explain the six purses in his squad car to his sergeant. Mother Superior decides Raffles must go to the pound if his owner doesn't respond to a Lost Dog ad. The Gypsy bids farewell to his cellmate, the Earl, and takes the paper with the ads. The Sisters spray purses with dog repellent, but Raffles lifts Monsignor Houk's wallet. Sister Bertrille prepares to take him to the pound, first flying up to return the Monsignor's wallet. The Gypsy finds the Sisters' ad, but Raffles is gone. Carmelita reports Jamie gone too. Sister Bertrille finds them and Raffles is reunited with his master. Later, Sister Bertrille reports the Gypsy has a good job and Raffles hasn't touched a purse or wallet in weeks. Then she finds a pile of hubcaps in the car.
