In Amboise, after a concert held at the Clos Lucé, a young virtuoso violinist is found dead in a position similar to Leonardo da Vinci's famous drawing: "Vitruvian man." Alban Dutertre (40 years old), Captain at the SR of Orléans, and Bérénice Amarillo (30 years old), Lieutenant at the Amboise gendarmerie, will investigate a series of murders that refer to the works of the master Leonardo da Vinci. Through these scenes, the murderer seems to be imitating the da Vinci-inspired drawings of Cecilia Rossi, a young artist who has been missing for 3 months and whose body the officers will soon find.
