A mysterious giant ape has appeared in the forests of northern India after a massive earthquake. The owner of a Hong Kong entertainment company, Lu Tien, is interested in capturing the ape for use in a global commercial show, or to make a taxidermy of it, which would be worth a fortune. At the same time, a young explorer, Chen Zhengfeng, also wants to go to India. Tien learns that he is more familiar with the road and invites him to cooperate with him. He will be responsible for the cost of the trip, but the ape belongs to him after the capture, so Zhengfeng eventually refuses to cooperate with him. At that time, Zhengfeng is in love with the diva Wang Cuihua. Chen Zhengfeng's younger brother, Shiyu, is a popular songwriter and a womanizer. In order to get a song written by him and become famous, Cuihua offers herself to Shiyu. Inspired by this, Zhengfeng agrees to Tien’s offer and teams up to go to India.
Under the guidance of a local guide, the expedition team is led through the forest, which is deserted, and climbs up cliffs and through lakes and swamps, where they are attacked by elephants, tigers and poisonous snakes. When the unconscious Zhengfeng is attacked by the ape, a beautiful wild girl named Ah-wei intervenes. It turns out that the girl's parents were originally explorers, but their parents were killed in a storm while exploring in a small plane, leaving behind 4-year-old Ah-wei, who was rescued and raised by the ape whom she named Ah-wang (“Utam” in the English dub). Ah-wei gradually grows up, and has fun with the forest animals, such as cheetahs and elephants, together.
Zhengfeng and Ah-wei fall in love with each other and become good friends with Ah-wang. Zhengfeng decides to take them back to the civilized world, but he falls into a trap set by Tien and is forced to lock Ah-wang on a boat, which sails back to Hong Kong across the Indian Ocean. When Ah-wei sees Ah-wang being humiliated, she is upset and sees Cuihua crying in Zhengfeng's arms, so she turns around and escapes. Ah-wang performs at a stadium in Hong Kong under the arrangement of Tien. Ah-wei rushes to the stadium and throws herself into Ah-wang’s arms with tears in her eyes. When Tien tries to rape Ah-wei, Utam witnesses through the window and breaks free from his shackles in anger, and Tien flees in a panic. The angry Ah-wang wreaks havoc and climbs up Hong Kong's tallest building, the Connaught Centre. The army mobilizes helicopters and armored vehicles to kill Ah-wang before Zhengfeng and Ah-wei can stop his rampage first.
