In order to escape Deeti's in-laws, she and Kalua become indentured servants, travelling on the Ibis.

This is not acceptable to the high caste villagers. Deeti looks almost certain to meet her doom when she is forced to consider sati ritual (immolation on her husband's funeral pyre) as the only option in the face of threats of more rapes by the brother-in-law, but then Kalua, the untouchable caste ox man from the neighbouring village, comes to her rescue. When her husband dies, Deeti sends Kabutri to stay with relatives. This brother-in-law is the real father of Deeti's daughter Kabutri. Married to Hukam Singh, a crippled worker in the Ghazipur Opium Factory, the unfortunate Deeti figures out that on her wedding night, she was drugged with opium by her mother-in-law, so that her brother-in-law could rape her and consummate the marriage in place of her impotent husband.

The story begins with Deeti, a simple, pious lady, caring mother and an efficient housewife. The novel interweaves the stories of a number of characters, who all, in the latter half of the novel, find themselves taking passage from Calcutta to Mauritius on a schooner named the Ibis. He portrays the characters as poppy seeds emanating in large numbers from the field to form a sea, where every single seed is uncertain about its future. The author compares the Ganges to the Nile, the lifeline of the Egyptian civilization, attributing the provenance and growth of these civilizations to these selfless, ever-flowing bodies. The story is set prior to the First Opium War, on the banks of the holy river Ganges and in Calcutta. The main characters include Deeti, an ordinary village woman, an " octoroon" American sailor named Zachary Reid, an Indian rajah / zamindar called Neel Rattan Halder, and Benjamin Burnham, an evangelist opium trader. In the words of Rajnish Mishra, "the Ibis trilogy is Ghosh's most vehement indictment of the source of imperialism and colonialism". It is the first volume of the Ibis trilogy. Sea of Poppies (2008) is a novel by Indian novelist Amitav Ghosh which was shortlisted for the Man Booker Prize in 2008.
