Bruno (Antonio Zavatteri), a 45-year-old police detective, is investigating complex financial tax crimes and corporate fraud within a bank/company. The case turns dark when the primary suspect (an auditor named Metelli / bank president Romoli) is discovered dead in a hotel room under suspicious asphyxiation circumstances—bound with stockings, a cable, and a trash bag over his head. As Bruno navigates the investigation, he immerses himself in interviews with key figures surrounding the deceased, including De Angelis, unraveling the psychological dimensions and hidden desires of the suspects while confronting his own personal boundaries.
