Toomai (Sabu), a young boy growing up in India, longs to become a hunter. In the meantime, he helps his mahout (elephant driver) father with Kala Nag, a large elephant that has been in their family for four generations.

Petersen (Walter Hudd) hires the father and Kala Nag, among others, for a large annual government roundup of wild elephants to be tamed and put to work. Amused by Toomai and learning that he has no one but his father to look after him, Petersen allows the boy to come too.

Strangely, no elephants have been seen in the region in a while, so Petersen has staked his reputation on a guess that they will be found further north. However, six weeks of hunting prove fruitless. He is ready to give up, but his right-hand man, Machua Appa (Allan Jeayes), persuades him to keep hunting for another month. When the other hired natives learn of Toomai's ambition, they mock him, telling him that he will become a hunter only when he sees the elephants dance (a myth).
