Cornwall, 1790. Ross Poldark faces the darkest hour of his life. Accused of wrecking two ships, he is to stand trial at the Bodmin Assizes. Despite their stormy married life, Demelza has tried to rally support for her husband. But there are enemies in plenty who would be happy to see Ross convicted, not least George Warleggan, the powerful banker whose personal rivalry with Ross grows ever more intense.

Demelza Carne, the impoverished miner's daughter Ross Poldark rescued from a fairground rabble, is now his wife. But the events of these turbulent years test their marriage and their love. Demelza's efforts to adapt to the ways of the gentry - and her husband - bring her confusion and heartache despite her joy in the birth of their first child. Ross begins a bitter struggle for the rights of the mining communities - and sows the seed of an enduring enmity with powerful George Warleggan.

Tired from a grim war in America, Ross Poldark returns to his land and his family. But the joyful homecoming he has anticipated turns sour, for his father is dead, his estate is derelict, and the girl he loves is engaged to his cousin. But his sympathy for the destitute miners and farmers of the district leads him to rescue a half-starved urchin girl from a fairground brawl and take her home - an act which alters the whole course of his life....
