The incredible true story of a man who wore a sanitary pad, was mocked and ridiculed by the world but went on to create a revolution. A welder by profession, in one of India's beautiful and conservative temple towns, Lakshmikant (Akshay Kumar), newly married, sees Gayatri (Radhika Apte), his wife, using a dirty cloth during her periods. Not very well-to-do, he borrows money and buys her a pack of Sanitary pads. Gayatri is firm that they can't afford this indulgence and forces him to return it. Worried about the health of his wife and being Innovative by nature, Lakshmikant decides to make his own pad and fails. The pad now becomes his obsession. The town thinks he is a pervert. His wife leaves him. But nothing can take away his single minded focus of making an affordable pad. Based on the life of Arunachalam Muruganantham, 'Pad Man' is the story of an illiterate genius who made care and concern for a woman's menstrual health a major national movement.
