The young Bruno Mulas is found dead in the street, a few meters from the apartment he shared with his friend Gavino. Several posts on Facebook seem to point to a suicide, but Gavino does not think so. Bruno's parents are bewildered, his friends seem to be entrenched in silence. The case becomes an obsession for the protagonist, the crime journalist Nereo Carta, who remains entangled in a network of relationships in which no one is what they seem. The story, structured as a mystery-noir, deals with themes and topics related to the cosmos of young people. Suicide, for example, to which the protagonist dedicates extensive reflections, as well as mental illness and existential distress because of the inability to find a position and meaning in one's life.
