Laxmikanth Chauhan is a partner/tool operator in a workshop. He is against how women in his society are treated during their menses. When he marries he decides to make things better for his wife Gayatri; he purchases sanitary napkins for her because she has been using dirty, unhygienic rags. Gayatri asks him to return the napkins because they're too expensive. He decides to try to make them himself for less money and convinces her to use them, but they're not better; he tries to improve them but fails. Laxmi is then criticized in his village for taking up such initiative; his family disowns him and he is forced to leave his village. But his hopes survive and he researches how to make low-cost sanitary napkins for the betterment of women.
