The first time that Mélanie met Clara, Mélanie was stunned by Clara's sense of authority, and Clara was struck by Mélanie's pink, glittery nails, which shimmered in the dark. "She looks like a child," thought the first. "She looks like a doll," pondered the second.

These two women, both of the same generation and exposed to the same media throughout their lives, could not be more different in adulthood. Mélanie is a social media superstar, broadcasting her children's daily lives on a family YouTube channel. Clara is a young police officer, assigned to the case after Mélanie's daughter Kimmy is abducted.
