The abolition of slavery in the British Caribbean in 1834 prompts Gillanders, Arbuthnot & Company in Calcutta, a part of the East India Company, to recruit Coolies from India to fill the resulting labor void. The company hires Sinha, a fierce small-timer to sell dreams of El Dorado to the unsuspecting, impoverished Coolies who are signed to five-year contracts as indentured servants. Upon the Coolies' arrival in British Guiana in 1838, the British planters promptly enslave them to ensure that the growth of sugar in the British West Indies will continue uninterrupted. John Scoble of the British and Foreign Anti Slavery Society arrives on the colony a year later to discover a new form of slavery; this time on the backs of Indians.

In the summer of 1985, the San Francisco police unearthed a grisly discovery. The bodies of 25 victims, men, women and children were found, on a remote ranch along with a homemade dungeon and explicit videotapes. Two men were arrested for the horrific murders, but only one would face prosecution. This turned out to be one of the most grim, devious and damning cases in California history. This is the true story of Charles Ng, the first Chinese serial killer in America.
