With more shares in Wheal Leisure, George uses his increased power to put a stop to the tunnel trying to reach Trevorgie. Ross begins to think that Mark Daniel might have come across a copper lode when hiding in Wheal Grace and Demelza continues her thrift by venturing out to fish whilst heavily pregnant, despite Ross forbidding her. Elizabeth visits George to keep him sweet, knowing he could bankrupt them at any time, but finds his proposition to spend more time together behind Francis back too high a price. Meanwhile, Dwight diagnoses an outbreak of scurvy in Sawle and, though he is still wary of her, Caroline thinks to impress him by buying oranges for his precious fisherfolk, and succeeds. Trencrom, the local crime-lord, offers Ross £200 to allow him to use Nampara Cove for smuggling and, with his plans for Wheal Leisure thwarted and desperate for money, Ross invites Demelza's anger by accepting. Verity meets her husband's daughter, who obviously hates her, but when his son James comes to visit Verity is overjoyed to discover he is both charming and happy to have a new mother. When George shows up at the Wheal Leisure shareholder meeting, Ross instructs Pascoe to sell half his shares in Wheal Leisure to realise £600 that, together with Francis £600, they can open Wheal Grace with. However, George reveals that he gave Francis the money for betraying Ross by revealing the Carnmore Copper Company shareholders names; Ross and George fight. Afterwards Ross bumps into Andrew Blamey and realises if he can get Francis to accept Blamey and forget the past (the dishonour of Verity's eloping with Blamey) then he can forgive Francis. Returning home, Ross discovers Demelza has gone fishing again and finds her struggling to get ashore, in the throes of labour. They bicker as he rescues her but she safely gives birth to a son, Jeremy, and the whole family celebrate both the birth and re-opening of Wheal Grace.
