Cornwall, towards the end of the 18th century. Ross Poldark sits for the borough of Truro as Member of Parliament - his time divided between London and Cornwall, his heart divided about his wife, Demelza.
His old feud with George Warleggan still flares - as does the illicit love between Morwenna and Drake, Demelza's brother.
Before the new century dawns, George and Ross will be drawn together by a loss greater than their rivalry - and Morwenna and Drake by a tragedy that brings them hope . . .
