Aidan Turner and Eleanor Tomlinson return to BBC One this evening from 9PM with the first episode of the fourth series of epic Cornish saga Poldark.
Following hot on the heels of the third series, the fourth instalment brings a host of new characters and worlds into play.
1796: Ross (Turner) must defend Cornwall from an empowered George Warleggan (Jack Farthing), and risks everything he holds dear as he embarks on a political journey which takes him to the nation's capital.
Demelza (Tomlinson) finds her loyalties torn, Elizabeth (Heida Reed) tries to strengthen her marriage, Morwenna (Ellise Chappell) continues to be oppressed by husband Reverend Ossie Whitworth (Christian Brassington), and the Enyses (Luke Norris and Gabriella Wilde) are tested as never before.
Aidan Turner reprises his role as the hero Ross Poldark alongside Eleanor Tomlinson as wife Demelza.
Also back for series four are Harry Richardson and Tom York as Drake and Sam Carne, Beatie Edney as Prudie and Josh Whitehouse as Lieutenant Hugh Armitage, who remains deeply in love with Demelza.
Plus powerful new characters enter the saga, Rebecca Front (War And Peace, The Thick Of It) is Lady Whitworth, Ossie’s formidable mother and Max Bennett (The Hollow Crown) is Monk Adderley, an unscrupulous society figure who is on a collision course with the Poldarks.
Finally, Ciara Charteris (Close To The Enemy) also joins the cast as Tholly’s wayward daughter Emma Tregirls who takes a shine to Demelza’s brother, the Methodist preacher Sam.
In tonight's episode, Prime Minister Pitt (Edward Bennett) calls an election and uncertainty grips the country.
While Ross watches Cornwall suffer under the power of Truro’s MP, George Warleggan (Jack Farthing), Demelza’s infidelity leaves her torn between her husband and a lovesick Hugh, who is set to rival George in the upcoming election.
The Enyses contemplate having a child and Elizabeth seeks the same to secure her marriage. Meanwhile, Morwenna (Ellise Chappell) uses Osborne’s (Christian Brassington) affair with her sister Rowella (Esme Coy) to keep the reverend’s advances at bay, and Demelza seeks to reconcile rival local Lords Falmouth and Basset.
A corn riot erupts in Truro, and Zacky’s (Tristan Sturrock) son Jago (Jack Riddiford) leads the charge. Sam Carne (Tom York) and Drake Carne (Harry Richardson) attempt to dissuade him but arrive too late, and a merchant is killed in the fighting. Tom Harry (Turlough Convery) tells George that the Carnes and Jago murdered the man, and Ross finds himself powerless to save his brothers-in-law...
Poldark continues tonight, 10 June on BBC One at 9PM
