In 1999, 89-year-old Hindu Saket Ram is on his death bed in Chennai, Tamil Nadu. He is being taken care of by his grandson Saket Ram Jr., a famous novelist who writes historical fiction, and their family doctor, Munawar. Saket Ram Jr explains how he grew up listening to his grandfather's stories and proceeds to narrate one of his grandfather's strange stories that he plans to use for his next novel. As his grandson narrates the story, the older Saket Ram relives it.

In 1946, Ram and his Pathan Muslim friend, Amjad Ali Khan are archaeologists working together under Mortimer Wheeler in Mohenjo-daro, Sind Province. Relations are good between the Indians and the English. Ram and Amjad do not approve of the planned partition and the upcoming creation of Pakistan. Although many Indian Muslims plan to move to the new Dominion of Pakistan, Amjad decides to stay in India as he believes it is his homeland.

After the archaeological site is shut down out of fear of riots, young Ram returns to Calcutta, Bengal State to his wife, Aparna. On his way home, he witnesses the riots and chaos during Direct Action Day. While out to get some food, Ram manages to save an innocent Sikh girl from a Muslim mob. When he returns to his house, he is attacked and held hostage by his family tailor, Altaf and a group of Muslims. They rape Aparna, but upon discovering that the police are entering the building, slit Aparna's throat and flee. Unable to cope with his tragic loss, Ram takes his gun and attempts to follow them. He manages to find Altaf, who begs for mercy, although Ram kills him.

Ram continues to shoot at Muslims committing violence in the streets until he runs into Shriram Abhyankar, a Thanjavur Marathi who is leading a group of a Hindus. Realising that they are both Hindu and thus not enemies, Abhyankar offers Ram a chance to join his militia. Abhyankar informs Ram that the individual responsible is none other than Mohandas Karamchand Gandhi and gives him a banned book on anti-Gandhi rhetoric to read.

In 1947, now having returned to his hometown of Thanjavur, Madras Province, Ram's brother Bhashyam and sister Vasantha urge him to remarry. He is then married to the daughter of family friends, Mythili. While his wedding is being celebrated across the village, Ram tells his childhood friends Vedha and Yegham that he has no reason to be happy since the world's biggest political divorce is going on with the partition of India. During his first night, he learns that Mythili, like her family, are supporters of Gandhi and that the Mahatma will be visiting Calcutta a few days later on the anniversary of the bloody riots.
