Gujarat, 1964. The agrarian system of renewable annual contract mandates fulltime labour on the houses and farms of landlords. In these bleak circumstances, Iso, a tanner by birth, graduates from being a child labourer to an adult serf on the estate of Mavaji. His life is one of humiliation, hunger and drudgery, and the only respite comes in the form of Diwali, Mavaji’s daughter. Between them exists a physical relationship that is shrouded in secrecy, shame and fear. Even as Iso creates distance between them, a chance encounter turns to violence and tragedy, and he faces the brutal sword of caste patriarchy.
