The first promo picture of "Poldark" season 3 has been released online. Details about the first scene of the show this year have also been released. The series will return in October.

The picture (see below) shows Ross (Aidan Turner) and Demelza (Eleanor Tomlinson) standing together. The post also reveals the release date of the show: Oct 1.

Meanwhile, details of the opening scene of the premiere episode have been posted by Radio Times. The scene shows a pregnant Elizabeth (Heida Reed) on a horse near a cliff top. She seems to be in need of a rescue because she has lost control of her horse.

Ross spots Elizabeth and races to rescue her. The scene ends here, but the report notes it isn’t hard to guess the outcome. Demelza and her husband haven’t had much time to heal after the two came together last season.

A night of passion between Ross and Elizabeth was the cause of the big fight, and now, this pregnancy is sure to add to the complication. A report by Metro reports that the father of the unborn child will be a mystery this year. Without sophisticated equipment for a paternity test during this time, it is impossible for anyone to tell who the child’s father is.

This will have a big impact on the mind of George Warleggan (Jack Farthing), who is at war with Ross. Farthing revealed that his character has become “worse," but the audience will see that he has grown. “You see more of him emotionally, his vulnerability,” the actor said.

Demelza, on the other, hand has moved on, according to Tomlinson. At the start of “Poldark” season 3, she will be seen working together with her husband, whom she still loves, as a team.
