[3] Notable for featuring one of only a handful of screenplays co-written by UK author Leslie Charteris, creator of the pulp fiction character Simon Templar (a.k.a., The Saint).

Due to a shortage of animals in American zoos following World War II, Tanya Rawlins, a big-game "huntress," Carl Marley, her financial backer and Paul Weir, a cruel trail boss, are given permission by King Farrod, to capture a male and female of each species of animal on his land.

Farrod is shot in the back and killed, and Suli is thrown into a pit full of crocodiles, but, unknown to all watching, he lands on a hidden ledge and is knocked unconscious.

When Tarzan finds out, he returns the flashlight, retrieves the cubs, and calls all the animals from King Farrod's land across the river to his part of the jungle.

When the hunters begin trapping on his side of the river, Tarzan and Boy sneak into their camp at night, take their guns and hide them in a cave behind a waterfall.
