Antonio comes across a love letter addressed to Pablo, signed by Juan, but which in fact was written by Pablo to himself. The letter makes Antonio fall into a jealous rage, but he has to return to his native Andalusia where he lives with his domineering German mother. As he promised, Pablo sends Antonio a letter signed Laura P, the name of a character inspired by his sister in a script he is writing. In his letter, Pablo tells Antonio that he loves Juan and intends to join him. However, Antonio, who is jealous and wants to get rid of Juan, gets there first. Antonio wants to possess everything that belongs to Pablo and tries to have sex with Juan. When Juan rebukes his advances, Antonio throws him off a cliff. After killing his rival, Antonio quickly heads for his hometown. Pablo becomes a suspect of the crime because the police have found in Juan's fist a piece of clothing that matches a distinctive shirt owned by Pablo. In fact, Antonio was wearing an exact replica when he killed Juan.
