In British-ruled Kenya in 1945, the Kikuyu people live and work in relative harmony with the white settlers under the watchful, mostly benevolent hand of Henry McKenzie Walter Fitzgerald. They follow their own religious beliefs, which prohibit violence against the settlers, and they strive to keep peace within a rigid colonial framework. Henry’s son Peter Rock Hudson grows up alongside Kimani Sidney Poitier, a Black farm worker who has become almost like a brother after the death of Henry’s wife. When Kimani asks to borrow a rifle to join a lion hunt, Peter’s brother-in-law Jeff Newton Robert Beatty slaps him and reminds him that the gun—and their friendship—are not his to claim. Kimani is humiliated and disappears, only to be found injured after his foot is trapped; Peter carries him back to the camp on his own back, a gesture that underscores their fragile bond. Kimani quietly suggests they shed the roles of master and serf, but Peter firmly rejects any cure that would reduce their relationship to power and subservience.
Back at the black settlement, Kimani’s father, Karanja Ken Renard, shocks everyone by ordering the murder of a newborn whose feet were born first—a sign the tribe regards as a curse. Karanja is arrested and jailed, provoking Henry to argue with the Crown consul about preserving the elders’ authority and the tribe’s way of life, lest the younger generation grow to scorn their own customs and the colonial Christian God alike. Henry, Peter, and Kimani visit the old man in jail, where Karanja gives Henry a sacred stone and urges Kimani to become the farm’s headman. Kimani refuses to spend his life as a white man’s slave, choosing instead to hold onto his own identity and loyalties.
One night, moved by moral outrage at the injustices around him, Kimani attends a clandestine Mau Mau meeting. Njogu Juano Hernández, the group’s leader, asks Kimani to prove his fidelity by stealing rifles. After a black houseboy is killed during the raid, Kimani is torn between loyalty to the McKenzies and allegiance to the Mau Mau. Njogu insists Kimani must stay, warning that the police will connect him to the crime. > it is your own hatred that you see in others. <
Years pass to 1952, and Peter—now the safari leader who supplements the shrinking farm income—welcomes Holly Keith Dana Wynter home after she studies abroad. Kenya’s tensions rise, and Henry and other settlers grow wary of the disappearances of many workers, though the women stay silent out of fear. Kimani endures the Mau Mau oath, receiving seven gashes on his arm, drinking sheep’s blood, and swearing to drive the Europeans from Kenya at any cost. He asks Njogu for permission to marry Njogu’s daughter, but the elder refuses to perform a Christian ceremony. On their wedding night, Peter and Holly celebrate their union while the Mau Mau raid the McKenzie farmhouse, killing Jeff Newton Robert Beatty and two of his three children, and wounding Elizabeth Wendy Hiller. Elizabeth—pregnant with Jeff’s child—must find safety, and Holly pleads with Peter to leave the country, but he cannot abandon his land.
As colonial authorities declare a state of emergency, Peter and their neighbor Joe Matson Michael Pate track down a Mau Mau camp and bombard it with a grenade. The Mau Mau surrender and are interned, enduring harsh interrogations that test their resolve. Peter, exhausted and morally unsettled, struggles to articulate his feelings to Holly, who wishes to stay in Africa she loves. When Henry and Peter return to the camp, they discover Joe torturing Njogu for information. Rather than escalate violence, Henry tries a different approach, presenting Njogu with the sacred stone and asking whether his gods would require the killing of innocent children. The thunderstorm that crosses the sky unsettles Njogu, and he concedes that if the gods cannot accept Mau Mau, then they cannot lead his people. He then names Kimani, now a Mau Mau general, as the leader of the attack on the McKenzie home.
As British forces crush the Mau Mau, Peter and the Black worker Lathela Ivan Dixon search for Kimani in the jungle. In Nairobi, Holly joins Peter at the hospital, where Elizabeth’s newborn child is born. Peter contemplates leaving with Holly, but she declares a deep attachment to Africa and their homeland. Joe and his armed men reach the spring first, and a brutal confrontation erupts. Kimani and his followers flee with an infant son into the forest, but Peter locates them in a cave and explains that they were betrayed by old loyalties and fears. When a confrontation arises, Kimani charges Peter with surrender to allow them both a chance to start anew; Peter refuses to relinquish the child. In a desperate struggle, Kimani lunges for a gun, but Peter wrestles it away and—holding Kimani at bay—begins to persuade him to surrender. Kimani slips into a pit trap, bamboo spikes piercing him. He begs Peter to throw the child to him to die with him, but Peter keeps the infant and carries it home to be raised with Elizabeth’s newborn, hoping a new generation might help bridge the chasm that has torn their world apart and heal the scars of East Africa.
