Matteo, a forty-year-old cartoonist, divides his time between work and family and nurtures the dream of publishing his own comic book starring Solo Valentine, a selfish superhero who uses his powers only for himself. He is married to Paola, a successful writer. A pleasant family picture, with three daughters, Virginia (9), Ginevra (6), Melania (2), and two dogs, is thrown into crisis when Sara, an old acquaintance of Matteo's, reappears with an offer he cannot refuse: to publish his comic book on condition that he moves to Paris.

Merano detective Andreas Mitterer already has enough problems – the last thing he needs is the "new partner" his superior, Giuseppe Malatesta, has chosen for him. The latter, however, has only the best of intentions, as Mitterer has been traumatized since the accidental death of his wife three years ago, a fact that hasn't gone unnoticed by the rest of his team: forensic pathologist Eva Rossi, forensic investigator Chiara Felice, and team assistant Giuliana Pucci.
