Based on the short stories by G K Chesterton, Father Brown follows the kindly cleric as he solves crimes in his community. Each episode sees the enigmatic priest investigate a crime in his own particular way, using intuition and psychology. Father Brown discovers the truth of a crime by looking into the truth of the soul - the passions, dark secrets, hidden desires. Many years spent hearing his parishioners' confessions have given him an uncanny insight into the origins of evil and the workings of the criminal mind. Father Brown is more interested in saving souls than in bringing the guilty to justice.
