Suranne Jones and Rose Leslie's Vigil returns for season 3 – and "most high-stakes mission yet"

The official synopsis reads: "Amy and Kirsten will need to catch the killer and diffuse a potential international confrontation, driven by a land-grab for energy and resources in the changing polar climate, with both their careers and relationship on the line."

Filming on the six-part season is set to get under way in Scotland later in the year, but there is no word yet on when the episodes might arrive on BBC One and iPlayer.

Speaking about the return, Jones said she was "sure it will be a thrill ride", while Leslie explained that "this time, Kirsten will get to pack her bags and join Amy on what's set to be Vigil's most high-stakes mission yet!".

Writer Tom Edge, who has penned all three seasons of the show, said: "I'm delighted that Suranne and Rose are returning for a new adventure.

"In our third season we travel to the frozen north, where the world's great powers are competing to secure advantages as the ice melts."
