Three times a day in a Parisian square, a curious modern-day crier announces the news items that are left in his box. Over the course of a few days he receives a number of disturbing and portentous messages of malicious intent, all of them referring to the Black Death.

Then charged and flea-bitten corpses are found. The press seizes on their plague-like symptoms, and the panic sets in.
