In real life, he can no longer achieve anything; he is under the thumb of his wife, works for a security company, and drinks himself into misery. The only one he loves unconditionally is his son. His promotion to security chief of a remote dam initially seems like a last chance. However, even before the small family moves, disaster begins to unfold. Unstoppable like a Greek tragedy, the calamity transforms the father into the "dam monster" and turns his son into a driven individual.
