He meets Vittoria, a mysterious and fascinating sex worker who leven though she claims to be already married.
The two begin a sexual relationship, while Vittoria is actually under the payroll of Manuel's bosses, among them is her fake husband who has planned on having her seduce him to obtain the names on the list.
