Plot

The film begins in the later years of G. D. Naidu's life, set in the late 1950s, when he is locked in a battle with the Income Tax Department, which demands that Naidu pay exorbitant tax. The film later moves to flashback, which recounts Naidu's story from his teenage years. Naidu develops an interest in a motorcycle, which he came across for the first time when a British official drove one to his village. He later works odd jobs to save money and succeeds in buying it.

The story follows Naidu working in a cotton mill, and later trying to start one himself. He later starts the United Motor Service, which grows into one of the large private bus service operators during the era. It showcases his inventions like India's first indigenous electric motor, the "Rasant" electric razor, a cheaper five-valve radio, India's first petrol engine car, amongst others. His fight against the British Raj earlier, and the battle with tax authorities post-independence, forms the crux of the remaining story.
