A baby boy is shipwrecked on the coast of Africa and is adopted by a gentle gorilla named Kala after losing his parents to a leopard attack. Raised among the gorillas, the boy, named Tarzan, grows up learning how to survive and communicate with the animals. Tarzan struggles to find his place within the gorilla tribe, facing skepticism from Kerchak, the group's leader and Kala's mate. When a British expedition led by Professor Porter and his daughter Jane arrives in the jungle, Tarzan encounters humans for the first time, sparking a curiosity about his origin. Jane and Tarzan quickly form a bond, leading to revelations about his human heritage.

Tarzan's world changes as he learns more about human society from the expedition team. Conflict arises with Clayton, the group's greedy hunter, whose selfish motives endanger the gorillas and threaten the harmony of the jungle. Torn between his loyalty to his gorilla family and his longing to unite with humans, Tarzan must navigate the complexities of both worlds. The decisions he makes will ultimately shape the future of the jungle and define his true identity.
