During the Vietnam War, Captain Willard of the US Army received an order from the headquarters to find Colonel Coates who had left the US Army. Coates once had a glorious history, but now he has fallen into madness. He established an independent kingdom in Vietnam, pursued a barbaric, bloody, and inhuman cruel rule, and from time to time carried out frantic, almost liar broadcast propaganda to the U.S. military. Willard’s order was to find Coates and bring him back or kill him. With this order, Willard led a small group of soldiers upstream along the Mekong River, through the jungle to Vietnam. In the process of searching for Colonel Coates, Willard almost traversed the entire Vietnam battlefield. He witnessed scenes of atrocities, horrors, killings and deaths, and was deeply shocked. In the constant killing, Willard almost became crazy.
Finally, Willard and his entourage have finally come to the kingdom of terror in Coates. They fell into the hands of Coates and were severely tortured. But this also allowed Willard to face Coates directly. Coates could have killed Willard, but he did not do so. With the help of Willard's hand, he completed the long-awaited death and was finally free from this crazy world. And Willard also deeply experienced the evil and darkness in human hearts, and the madness caused by evil. The natives knelt before him, and he had actually replaced Coates. Willard, who was sincerely disgusted with all this, picked up his companion and boarded the ship and left. The madness of Coates was stopped, but terror and killing were still going on frantically on the entire Vietnam battlefield.
