Mr. Whicher is hired by former Home Secretary Sir Edward Shore to investigate the violent threats made against his son Charles, who has recently returned from India with his family.

At the end of the 18th century, hundreds of Indian sailors, known as lascars, worked amongst European settlers in Aotearoa New Zealand - often under the gruesome working conditions of seal hunting gangs. The story follows a lascar, Dasa, who has been abandoned on the coast of Aotearoa NZ by the East India Company, alongside his sealing gang. When Dasa finds himself in the middle of a conflict between his abusive British superior and two Māori traders, he is faced with a choice: bend the knee or take a stand.
