What Happens in Tarzan’s Greatest Adventure: Full Plot Summary

The whole story of Tarzan’s Greatest Adventure (1959) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

Under the cover of night, the African village of Mantu is raided for its dynamite, and the village doctor and radio operator are fatally shot. Before dying, the operator gasps,

> Slade

over the shortwave radio.

The next morning, Tarzan, Gordon Scott, is awakened by drums that signal trouble. He leaves his treehouse and arrives at Mantu, where a funeral is being held for the fallen villagers. A police inspector informs Tarzan of the raid, and he sets out by canoe to catch his old nemesis Slade, Anthony Quayle, and his gang of raiders. Along the way, a small plane taunts Tarzan with low flyovers. But the engine stalls, and the aircraft crashes, dumping an American ex-fashion model, Angie, Sara Shane, into the river. Unwilling to abandon her, Tarzan brings Angie to the hunt.

Meanwhile, Slade and his quartet of thieves are just miles ahead, traveling by riverboat toward a secret diamond mine where they will use the stolen dynamite to excavate gems. When their boat malfunctions, the thieves begin to quarrel among themselves. One of them leaves the boat and later drowns in quicksand; another dies when Tarzan, who has now caught up with the raiders, nails him with a bow and arrow. Tarzan is wounded, and Angie tends to his wounds. She attempts to steal medical supplies from Slade's boat but is captured. Slade uses her to lure Tarzan into a trap, but the ploy fails, costing the life of another accomplice. Only Slade and a single ally, Kreiger, survive.

There is no honor among thieves, as Kreiger demonstrates when he tries to kill Slade after they reach the mine. Slade retaliates, and when Kreiger offers him all the diamonds if he lets him go, Slade remains unmoved and kills Kreiger. Back on the river, Tarzan is nursed back to health by Angie. He continues his quest to capture Slade, much to her displeasure. Tarzan thanks Angie for her help, and Tarzan, Gordon Scott, continues his pursuit toward a final confrontation with Slade.

High atop a river bluff, Slade fires rifle shots at Tarzan, who reaches him despite the gunfire. At first Slade gains the upper hand by lassoing Tarzan with a wire noose. However, Tarzan's strength and endurance win out, and he pushes Slade over the cliff onto the rocks below. Tarzan then travels back upriver to Mantu and his treehouse.

Q1

Why was Tarzan so determined to catch Slade after the village raid?

The radio operator in Mantu was fatally shot during the raid but managed to gasp "Slade" over the shortwave radio before dying. This identified Slade as the mastermind behind the attack. Additionally, the raiders had stolen dynamite and killed villagers, including the village doctor, which motivated Tarzan to protect his territory and bring the criminals to justice.

Foreshadowing: The raid occurs at night under cover of darkness, showing the raiders' deliberate effort to remain hidden until the operator's dying words expose them.

Q3

Why did the thieves start quarreling among themselves during the river journey?

Their riverboat malfunctioned mid-journey, causing tension and suspicion among the criminals. The breakdown created distrust as they approached the diamond mine, with each thief suspecting the others of sabotage or betrayal. This internal conflict led to one thief abandoning the boat entirely.

Foreshadowing: The thieves were already described as a "quartet of thieves" with mutual suspicion, and the boat failure amplified their existing mistrust.

Why did Slade use Angie as bait to lure Tarzan into a trap?

After Angie was captured trying to steal medical supplies from Slade's boat, Slade recognized an opportunity to use her as leverage. He believed Tarzan would come to rescue her, allowing Slade to set an ambush. The plan failed when the trap didn't work as intended, costing the life of another accomplice in the process.

Q6

Why did Kreiger try to kill Slade at the diamond mine?

When only Slade and Kreiger remained at the mine, Kreiger attempted to kill Slade to claim all the diamonds for himself. There was no honor among the thieves, and Kreiger decided eliminating his partner would be more profitable than sharing the loot. His betrayal was purely motivated by greed.

Foreshadowing: The narrative establishes early on that the thieves distrust one another, building toward this inevitable betrayal.

  • diamond mine

Q7

Why did Slade kill Kreiger even after being offered all the diamonds?

Q8

How was Tarzan able to defeat Slade despite being wounded earlier?

Tarzan was wounded during the pursuit, but Angie tended to his wounds and nursed him back to health. By the time he confronted Slade at the river bluff, he had recovered enough strength. In the final fight, Slade initially gained the upper hand by lassoing Tarzan with a wire noose, but Tarzan's superior strength and endurance allowed him to break free and push Slade over the cliff onto the rocks below.

Foreshadowing: Angie's medical care earlier in the story directly enables Tarzan's victory at the climax.
