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