After the release party for her debut novel, 19-year-old author Luise Nathan is found dead. Everything looks like a suicide at first. Publishing director Roland Häbler and editor Marvin Gess are reproaching each other: Could Luise not withstand the high pressure of expectations? Luise's book, which is about the socially disadvantaged teenage girl Luna, is a sensation in her eyes. Luise's mother Friederike, councilor for social affairs, on the other hand, cannot imagine that her strong daughter would commit suicide. The Frankfurt chief inspectors Anna Janneke and Paul Brix soon discovered that massive outside influences had led to the young woman's death. Outside of the publishing house, her investigations lead her to Luise's friend Nellie, who grows up in a less middle-class family with her mother Jessie and her little sister. Luise's novel is increasingly coming into focus: While Brix and Janneke initially devote themselves thoroughly to the victim's novel, when they investigate they become aware that it is based on the reality of the two girls and that it provides decisive traces .
