The BBC has released a trailer for its pandemic delayed drama Vigil, starring Suranne Jones and Shaun Evans

Airing just after the Line of Duty finale, and made by World Productions (who also brought us Line of Duty, Bodyguard and The Pembrokeshire Murders) Vigil is a detective story with a clear concept — a body is found on a submarine in service. It stars Suranne Jones, Rose Leslie, Shaun Evans, Martin Compston and Paterson Joseph, and will air on BBC One and BBC iPlayer later this year.

Here’s the plot in a nutshell:

The mysterious disappearance of a Scottish fishing trawler and a death on-board the submarine HMS Vigil bring the police into conflict with the Navy and British security services. DCI Amy Silva (Suranne Jones) and DS Kirsten Longacre (Rose Leslie) lead an investigation on land and at sea into a conspiracy that goes to the very heart of Britain’s national security.

The cast also includes Anjli Mohindra, Connor Swindells, Adam James, Gary Lewis, Stephen Dillane, Lolita Chakrabarti, Daniel Portman, Lorne MacFadyen and Lauren Lyle.

The six-part thriller was written and created by Bafta-nominated writer Tom Edge and filmed in Scotland. If you missed the broadcast, the trailer is still available to watch and you can also see some new images in the press release.
