Sundown is a 1941 American black-and-white World War II film, produced by Jack Moss and Walter Wanger, directed by Henry Hathaway, and starring Gene Tierney, Bruce Cabot and George Sanders. The film was released by United Artists. Against a World War II backdrop, Sundown’s adventure story, set in British East Africa, was well received by critics, earning three Academy Award nominations, but it was a failure at the box office.

Plot
An aircraft lands in Kenya near Rhino Rock, and Zia (Gene Tierney), disembarks and is met by a caravan, her caravan. In Manieka, British East Africa, Bill Crawford (Bruce Cabot), District Commissioner, contacts the governor at Nairobi, requesting a month-long furlough to study the Senshi, a local tribe. His colleague, Lt. Roddy Turner (Reginald Gardiner), sends a message to the governor to cancel the furlough as the Senshi are becoming hostile.

Two aircraft land at Manieka, bringing both rifles and Major Coombes (George Sanders), the Governor’s agent. Coombes tells Crawford that he is taking control of the outpost. When he finds Pallini (Joseph Calleia), officially an Italian prisoner of war, but unofficially the chef, Coombes wants Pollini put into restraints. He then asks Crawford why he wants a furlough, saying that someone is smuggling rifles to the Senshi.

Dutch engineer Jan Kuypens (Carl Esmond), working with the Italian government, is making a mineral survey of the area. Coombes suggests that Kuypens instead file his report with the British; he agrees.

A local trader named Abdi Hammud (Marc Lawrence) sets up an ambush of the British troops, but Crawford and his men are able to stop the attack. Zia, the daughter of the late Abu Kalli, who now runs the family network of trading posts in East Africa, arrives at the outpost.

Pallini has known Zia for many years, and on Pallini’s birthday, the outpost decides to throw him a party. The men make sure they invite Zia, but when she arrives, she must sit at a segregated table because by native custom she is considered a half-breed. Crawford sits with her and discovers that she is African.

The locals believe that one of the six white men will die that night. But there are only five of them at the party. When the white hunter, Dewey (Harry Carey), arrives, everyone else suddenly disappears. Two locals shoot at Crawford, but they miss, while Zia is grazed by a bullet. One of the attackers is killed and turns out to be the trader Hammud, responsible for the earlier ambush.

The suspicious Coombes orders Zia to leave the outpost, despite her slight wound. Kuypens confronts Zia in her quarters, who quickly recognizes his German accent. Kuypens is a Nazi agent who is bringing in rifles to arm the Senshi. She agrees to go with him, but passes a warning message to Pallini to give to Crawford. Before Pallini is able to deliver it, Kuypens kills him. Pallini becomes the one (of the six) fated to die that night.

The men find his body and Crawford decides to pursue Kuypens. Crawford confers with Dewey on where Kuypens will go. His rock samples, being volcanic, lead Crawford and Dewey to a geographic area they know. Their armed reinforcements follow shortly behind.

Zia is taken to a large cave complex where the rifles are being prepared. Crawford and Dewey find one of the arms stores and manage to blow up some rifles and ammunition. They also find the large cave complex; Dewey goes back to bring up their reinforcements.

Kuypens informs Zia that he knows that she is actually the daughter of Graham Fletcher, who, along with her mother, died when Zia was just two years old. Abu Kalli adopted her and raised her as an Arab.

Crawford is captured, and is placed in a large cell with Zia, who tells him that the Senshi will attack Marieka the following day. Crawford suspects that she is working with Kuypens, but she finally convinces him that he is wrong. The two escape by tricking their guards, but a shoot-out between them, Kuypens, and the guards ends with Zia being captured. Crawford plays dead, then overpowers the guard sent to finish him off.

Coombes and Dewey arrive with the British reinforcements, foiling the attack on Marieka. During the battle, Coombes is able to shoot Kuypens, but not before the Nazi agent fatally wounds him.

Later in London, Zia and Crawford are married before attending a large memorial service for Major Coombes. Afterward, they make their plans to return to Africa.
