Bishop Hemmelrath transfers father Braun to St. Florian, a poor parish in the Saarland's derelict mining region. The local 'Palomas' men choir is linked with the keeping of pigeons, who also deliver quite some love - (to Braun's maid Margot) and other notes. Shortly after, chorister Adolf Zwickel and a local Casanova suspiciously fall to their deaths. Meanwhile the bishop's ambitious deputy, monsignor Mühlich, traced to the parish the pigeon which delivered a ransom note for a huge, precious, obviously stolen church treasure, so he's sent to pay it discretely. Only Braun can make sense of all the confusing sets of pigeon messages.
