Heart of Darkness recap

While waiting on the Thames, the seaman Marlow recalls piloting a Belgian trading company's steamer into the Congo to retrieve Kurtz, a renowned ivory agent. The company's claims of progress are contradicted by waste, coercion, and suffering at its stations. After repairing a wrecked boat, Marlow travels upriver through fog and an attack that kills his helmsman. At the Inner Station he finds that Kurtz has used eloquence, intimidation, and local devotion to place himself beyond restraint while amassing ivory. Gravely ill, Kurtz is removed by the company despite trying to return to his followers. He dies on the downstream voyage after offering a final, despairing assessment of his life. Back in Europe, Marlow gives Kurtz's papers and photograph to his fiancee. When she asks about Kurtz's last words, he protects her idealized memory with a lie. The tale leaves the supposed divide between European civilization and the wilderness morally overturned.

Five men wait for the tide aboard the Nellie on the Thames, where Marlow begins telling of the time he sought command of a riverboat in Africa. Through his aunt's connections he joins a Continental ivory-trading company and travels to its territory in the Congo. The lofty language surrounding the enterprise is immediately contradicted by administrative absurdity, reckless destruction, forced labor, and dying African workers. At the Outer Station, an immaculately dressed accountant first tells Marlow about Kurtz, the company's most productive and promising agent, who is stationed far inland. Marlow then makes a difficult overland trek to Central Station and learns that his assigned steamer has sunk. The station manager says Kurtz is ill and stresses the need to reach him, but Marlow must first spend months salvaging and repairing the boat. The manager and other employees watch Kurtz's influence with a mixture of expectation and resentment, while Marlow becomes increasingly curious about a man he knows only through competing reputations.

After completing the repairs, Marlow pilots the steamer upriver with the manager, armed company agents, and an African crew whose restraint he comes to respect. Signs of the company's supposedly civilizing work recede, and the river journey becomes slow and oppressive. At an abandoned hut Marlow finds firewood, a warning to approach cautiously, and an old seamanship manual whose handwritten notes fascinate him. Near the Inner Station, thick fog leaves the boat nearly blind. Hidden attackers then fire on it from the bank. Marlow's helmsman is killed, but blasts from the steam whistle frighten the attackers away. Believing the station may already have been overwhelmed, Marlow fears that Kurtz is dead and recognizes how strongly he has come to anticipate hearing the man's voice. On reaching the station, he meets a young Russian trader in patched clothes. The Russian identifies the abandoned hut as his and speaks of Kurtz with intense devotion, insisting that their conversations changed his life.

The Russian explains that Kurtz has acquired ivory through raids and has made himself the center of a local following. Marlow sees severed heads displayed near the house and realizes that Kurtz's exceptional gifts have operated without any effective restraint. Although gravely ill, Kurtz still commands the people around the station. The company's men carry him to the steamer; that night he crawls away toward his followers, but Marlow intercepts him and persuades him to return. As the boat departs, the Russian slips away and a magnificent African woman watches from the bank. During the downstream voyage Kurtz gives Marlow papers to preserve from the manager. He dies soon afterward, ending his life with a stark expression of horror at what he has seen and become. Marlow nearly dies of illness too, then returns to Europe. He yields some of Kurtz's documents to company and political claimants but takes the personal letters and photograph to Kurtz's fiancee. She still believes Kurtz was noble and asks for his final words. Marlow lies that Kurtz spoke her name, preserving her illusion. On the Nellie, the Thames itself now seems to lead into the darkness described by his tale.

Kurtz dies aboard the steamer during the journey downriver after entrusting Marlow with a packet of papers. Marlow survives a severe illness and returns to Europe, where several people seek control of Kurtz's documents and reputation. He distributes some of the papers but keeps personal letters and a photograph for Kurtz's fiancee. When Marlow visits her, she remains devoted to an idealized memory of Kurtz and asks what he said at the end. Unable to destroy her belief, Marlow tells her that Kurtz's final word was her name, concealing the bleak judgment Kurtz actually uttered. Back aboard the Nellie, Marlow falls silent. The frame narrator looks down the Thames, now associated with the moral darkness Marlow found not only in the Congo but within European power and human ambition.
