The Invisible Guest

Businessman Adrián Doria is out on bail after being arrested for the murder of his lover, Laura Vidal. His lawyer, Félix Leiva, hires a famous attorney named Virginia Goodman, who visits him at his apartment with the news that the prosecutor has found a witness who will be testifying in front of a judge soon; they have just three hours to come up with a defense, so Virginia urges Adrián to tell her the whole truth. Adrián tells Virginia how he and Laura had ended their affair but received a call blackmailing them to come to a rural hotel with €100,000. At the hotel, Adrián was knocked unconscious and awoke to find Laura dead in the bathroom. With the door and the windows locked from inside, the police are quick to declare Adrián as the prime suspect.
