 A retired detective superintendent returns to his old precinct after more than six years - as a priest! But no sooner has he taken over his parish in the roughest part of town than his past catches up with him and, willy-nilly, he is involved in a series of criminal cases. Really this is the last thing he is looking for and he does his best to keep out of it. But his concern for the welfare of those living in the seedy part of town around the railway station gets the better of him time and again. Thus, armed with his charm, his knowledge of human nature and the keen eye of a policeman he comes to the aid of the troubled and succeeds brilliantly in resolving the frequently tricky cases.
