Young Pinto has from his childhood been an out-of-the box thinker, finding solutions in his everyday surroundings to a myriad ancient global problems. A certain machine he invents in his childhood makes him a hero in his village but it's not sufficient to change the mindset of naysayers for Pinto to pursue his career in hardcore science.

Pinto Has an Idea is the tale of Dr Pinto, a small-town boy, an IITian and a scientist working in MIT, who suddenly experiences a life-changing revelation in the early days of his research, throwing away his work on theoretical physics and setting out to solve the practical everyday problems of the world he lives in.

Returning to his native India, he finds his noble quest beset by unexpected adversaries, obstacles and trials, but emerges triumphant from each battle.

Pinto does not like to appear a romantic person, and keeps women at bay. But when Lavanya returns to haunt his life, and eventually shoe-horns him into marriage, he obligingly falls in love. Because Lavanya is not just a pretty face, she's his partner in research. And Pinto, a newbie in romance, discovers a whole new craze.
But life takes directions never aimed for. Pinto is on the road to becoming rich and famous. He invents a mechanism to eradicate corruption in the land, and in that process moves towards politics. That impinges on the couple's relationship so severely that Lavanya disappears suddenly without telling Pinto. Why does she leave their child with Pinto? Will he lose his greatest 'idea', Lavanya, and thereby, himself? Sure, Pinto's ideas bring dramatic changes to society. But how much romance can a scientist handle as well?
