Shankar is an honest and efficient police officer. Shanthi is a humanist doctor. They have a love marriage but soon realize that their ways of thinking are very different. Over the course of their confrontations, Shankar begins to question himself and realizes that like terrorists, he also believes in violence. The incidents force him to question himself and how he comes to transform himself forms the story of Tamassu. Tamassu is a journey from violence to humanism. It is a story each one of us goes through. How much of what we think as right, really right? How much of what we do as our duty, really service? Agni Sreedhar weaves the story marvellously, touching upon issues of state sponsored religious riots, terrorism and the purity of human relationships which goes beyond all boundaries.
