In the midst of the chaos and madness of the Vietnam War, a captain from the Special Forces receives a mission that will take him into the heart of darkness. His objective is to find and eliminate Colonel Kurtz, a high-ranking officer who has lost his mind and established a kingdom in the jungle, where he rules with an iron fist and ruthless insanity. With his mind increasingly deteriorating, Kurtz has become an almost mythical figure, venerated by the natives and completely detached from conventional military morality.
The captain, accompanied by a diverse group of soldiers, embarks on a river journey along the perilous Mekong River, where they face guerrilla attacks, the surreal beauty and horror of the surroundings, and their own inner demons. As the journey unfolds, the horrors of war and psychological decay become increasingly evident, testing the sanity of all involved.
The story becomes a deep reflection on madness, power, and the impact of war on the human psyche, as the protagonist struggles to understand what it truly means to be human in a world that seems to have gone mad. In his quest for Kurtz, he discovers that the real enemy may lie within oneself, leaving the audience with an unsettling question: who is the true monster in this senseless war?
