Erectus

The phenomenon has started in the Kruger Nature Park in South Africa, and has soon spread throughout the world. Animals and plants are going backwards in evolution. Dogs become wolves, whales become land mammals and humans... Herds of Homo erectus begin to appear in New York, in Paris, in Geneva... Dozens of individuals with prominent jaws and covered in hair who have lost the ability to speak. Disoriented and unpredictable, they sow panic in the population. As scientist Anna Meunier launches a race against the clock to understand and stop this regression of humanity, and perhaps save the person who matters most to her, the same question is hovering around the world: what's behind this terrifying pandemic?
