With the country gripped by political uncertainty and fresh elections, Ross Poldark (Aidan Turner) seeks to challenge George Warleggan's stranglehold over Cornwall while also repairing his marriage with Demelza (Eleanor Tomlinson). Hugh Armitage remains in love with Demelza and is hopeful for more. Dr. Dwight Enys and Caroline plan to start a family while Elizabeth seeks another child to secure her own marriage to an ever-suspicious George. Meanwhile, Morwenna desperately tries to protect herself from Osborne's advances by threatening their son, and a heartbroken Drake is encouraged by his brother Sam to find new love.
