Vigil

Vigil is an adrenaline-fuelled new thriller that unravels a high-stakes conspiracy threatening the very heart of Britain's nuclear deterrent.

As this six-part drama commences, two seemingly disparate events - the disappearance of a Scottish fishing trawler and a death aboard a Trident nuclear submarine - bring the police into direct conflict with the Navy and British security services.

DCI Amy Silva is thrown into this highly charged situation, tasked with heading an investigation both on land and at sea. Finding her authority increasingly weakened by the forces at play around her, the brilliant but fragile Silva is also left questioning her own choices as she navigates personal trauma and loss.

This timely thriller takes viewers deep into the pitch-black icy waters of the Atlantic, to a place where tomorrow's geopolitical struggles are already being played out.
