El lamento de los girasoles

Movie? Comedy? Documentary? Sex-sociological analysis?? In any case, a unique tour of the essential questions of life: Why sexually attract us? What was the sexual revolution of women? What is the mandate of our genes? Is it mathematically impossible to hit in mate choice? Is marriage a risky business? And a fundamental question: why dinosaurs became extinct?

A mysterious shooter randomly kills innocent citizens in public; one after the other in broad daylight. All murders happen not far from the White House; not far from the President.
