The Katyn massacre, carried out by the Soviet NKVD in 1940, was only one of many unspeakable crimes committed by Stalin's ruthless executioners over three decades. The mass murder of thousands of Polish officers was part of a relentless purge, the secrets and details of which have only recently been partially revealed.

After delivery of a parcel, on leaving a restaurant, hotel or train, or following an exchange with the customer service department of your telephone operator, the same request: to rate. On a scale from 0 to 10, embellished with colors, or by awarding pretty, playful little stars. A simple, mechanical and painless action for the rater. But behind this harmless gesture lies a brutal management system, operated directly by the customer, without their knowledge. Even more worrying: without knowing it, we are all being rated, to feed the algorithms of opaque companies that claim to be able to predict the future. The film questions this invasion of rating systems, and the consequences of this practice for our individual realities and collective freedoms.

Since the defeat, the Nazis, who were the masters of the occupied zone, and the French State, which had been ruling the so-called free zone since Vichy, ordered the Jews to take a census. From the spring of 1941, whether they had been French for several generations or naturalized for a few years, foreigners who had taken refuge in France or stateless people who had been driven out of their country, they were put on file, arrested or threatened at any time. Some wrote to the administration, or directly to Marshal Pétain, who seemed to them to be the last resort. These requests are called Suppliques. Men, women, sometimes children, tried as best they could, by all means, to loosen the trap. They address themselves to their executioners, but they do not know it.
