Coral Kendall is an heiress to the Kingscote Silk Plantation in northern India in the last decade of the 1700s. Breaching cultural boundaries and shunning the scorn of her wealthy English family, she adopts a young orphaned boy, an "Untouchable" from the bottom of the Hindu class system, and brings him into her home. Despite their contrasting cultures and backgrounds, the bond of love that develops between Coral and Gem is that of a mother and son. But tragedy strikes when the boy is abducted and the body later found in the river.
