Father Brown is only too happy to interfere with the work of the police in solving tricky criminal cases, usually with resounding success. That's why the clergyman is transferred to a sleepy island called Abbott's Rock. At first, nothing happens there, but somehow Father Brown seems to be attracted to crime: Soon a gang of thieves is up to no good on the island. So Brown makes the headlines again, and is punitively transferred once more. This time he finds himself in a quiet Irish millionaire community.
With the help of God, the loveable safecracker Paul Wittkowski – aka “Cracker-Paulie” – manages to escape the clutches of the cops. He dresses up as a priest and ends up in a village, whose pastor is in dispute with an influential businessman. To help the pastor and a young widow, Paulie has to use his own special abilities. This work leads him back to the path of righteousness. He contacts the police and, after serving his time, starts a new life with the widow.
