Toofani Tarzan

Scientist Ramu and his wife Uma (Nazira) live with their four-year-old son Leher in the jungle where he carries out experiments. He has discovered the elixir of life. Lions attack their house killing him, while his wife goes mad with grief. Ramu's son, Leher, and their little dog Moti, escape with the help of a half-man, half-ape called Dada (Boman Shroff). Several people arrive in the jungle fifteen years later from the city.

One of them is Ramu's father with his adopted daughter, Leela. Bihari, one of the people in the group wants the formula for his own purpose. The formula was put in a pendant around Leher's neck by his father before he died. Leher now grown-up and known as Tarzan (John Cawas), has been brought up in the jungle and there are some amusing incidents between Leela and Tarzan, due to his lack of language skills. Tarzan saves Leela from Bihari's unwanted advances.

The story then moves to tribal cannibals trying to attack the group along with Tarzan, with ‘stunt scenes' involving the cast and animals like elephants, the dog Moti, lions and apes. The story ends with the grandfather re-uniting with Tarzan and the mentally unstable mother meeting up with them.
