After surviving their expedition to King Solomon's Mines,
Allan Quatermain and Jesse Huston have settled down in colonial Africa. They are engaged to be married and Jesse plans to travel to America for the wedding, but Quatermain is restless. A man chased by two strange masked men emerges from the jungle, and is recognized as one of Quatermain's friends Dumont. He is delirious and is cared for by Jesse and Quatermain, but at night, his pursuers return to kill him. Before he dies, Dumont tells Quatermain that his brother Robeson, supposedly lost, is alive, and that they have found the legendary "Lost City of Gold". Quatermain immediately starts preparing for an expedition to find Robeson. Jesse is furious and stalks off, but then realizes how important this is to Quatermain. Quatermain and Jesse are assisted by Umslopogaas, a fearless warrior and old friend of Quatermain's, to put together an expedition. Swarma, a spiritual guru, and five
Askari warriors accompany them. The group crosses a desert and reaches the Walls of Japora. Two Askari are lost when Swarma trips a boobytrap that opens a pit under the road to the city. Another member of the party is lost when savage Eshowe warriors attack the group. Many spears are thrown at Quatermain and his friends, but Umslopogaas deflects most of them with his giant axe. The remaining Askaris are lost in a subterranean river. Quatermain and his friends indeed discover the city. The inhabitants, both black and white, are friendly, and Quatermain meets with Robeson, seemingly in good health and at peace in the society. The city has two queens — the noble and beloved Nyleptha and her power-hungry sister Sorais. But the real leader is the evil High Priest Agon, feared by all. Quatermain raises the population against Agon and Sorais, who musters an army to recover the city by force. Quatermain realizes that they can make all the weapons they need out of gold, which is mined by the population. The final battle ends when, atop the temple, during a lightning storm, Quatermain uses Umslopogaas' axe to channel the lightning and melt the gold, causing it to flow off the side of the structure and pour over the attacking horde, turning Agon and his army into gold statues. Afterwards, Shawarma finally reveals himself and asking some water, and only to be thrown by Umslopogaas into the water fountain as the crowd laughing. Quatermain and Jesse finally kiss and celebrates their victory. ==Cast==
