Vigil: Series 3

Vigil is an adrenaline-fuelled thriller that unravels high-stakes conspiracies threatening the very heart of Britain’s defences. Suranne Jones and Rose Leslie return as DCI Amy Silva and DI Kirsten Longacre. Their new case takes them to a remote Arctic research station, where a member of a covert British special forces mission has been shot dead. 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.
