The Legend of Tarzan (2016)

Tarzan, having acclimated to life in London, is called back to his former home in the jungle to investigate the activities at a mining encampment. As a result of the Berlin Conference, the Congo is divided up between Belgium and the United Kingdom. The Belgian government is on the verge of bankruptcy, having gone into heavy debt to build a national railway and other infrastructure. King Leopold II of the Belgians decides to extract the Congo's mineral deposits, sending his envoy Léon Rom to secure the fabled diamonds of Opar. Rom's expedition is ambushed and massacred, with only Rom surviving. A tribal leader, Chief Mbonga, offers him the diamonds in exchange for Tarzan. In London, Tarzan, now known as John Clayton III, Lord Greystoke, is invited by King Leopold to visit the Congo and report on its development. An American envoy, George Washington Williams, reveals to him suspicions of the Congolese population being enslaved by the Belgians. Tarzan's wife Jane convinces him to accept the invitation, as she grew up in Africa. Tarzan, Jane, and Williams travel to the Congo and encounter a tribal village that recognizes them. Rom and his mercenaries attack the village, kidnapping Tarzan and Jane. Williams rescues Tarzan, and with the help of the tribe's warriors, they pursue Rom. Along the way, they intercept a Belgian military train carrying captured slaves and uncover King Leopold's plans to subdue the Congo and mine its wealth. Tarzan reconciles with the leader of his old tribe, battles Mbonga and his tribe, and saves Jane from Rom. They trigger a stampede of wildebeest to destroy a town and distract the soldiers, allowing Tarzan to rescue Jane and defeat Rom. Williams presents evidence exposing the slave trade in the Congo, and Tarzan and Jane settle in Africa.
