Sol de medianoche

Manolo is a private detective specializing in adultery cases and working in a beach-and-tourist ghetto of San Juan, Puerto Rico. He appears to live tortured by the murder of his twin-brother Frank --which event took place just a few years before and for which he was formally accused. Then, following his motto of "betrayal is my business", Manolo spies on and records the affair of past friends Migdalia and Carlos --a case he scores by calling Migdalia's Mother and getting her to hire him-- while, in a parallel tangent, he attempts to mentally reconstruct the events that culminated in Frank's murder.
