Mahendra Saini (Rajesh Tailang) is a chain-wallah who peddles his zipper repair skills on the streets of Delhi. Armed with a megaphone, Mahendra markets himself to anyone within earshot. As with any service-oriented business, location is everything. So when his usual beat stops being fruitful, Mahendra’s 12-year old son, Siddharth, is recruited to earn a second income. Mahendra’s brother-in-law, Ranjit (Anurag Arora) suggests a trolley factory where child labor, though illegal, is a means of income. Siddharth travels to the factory unharmed, but two weeks before he is to return home, he disappears.
