From the creators of Line of Duty, Vigil investigates the mysterious disappearance of a Scottish fishing trawler and a death on-board the submarine HMS Vigil, which bring the police into conflict with the Navy and British security services.

 DCI Amy Silva (BAFTA winner Suranne Jones from Gentleman Jack and Doctor Foster) and DS Kirsten Longacre (BAFTA winner Rose Leslie from Game of Thrones, The Good Fight) lead an investigation on land and at sea into a conspiracy that goes to the very heart of Britain's national security.

 Vigil's stellar ensemble cast also features Emmy nominee Stephen Dillane (Stannis in Game of Thrones), Anjli Mohindra (Bodyguard), Shaun Evans (Morse in Endeavour), MTV Movie Awards nominee Connor Swindells (Adam in Sex Education) and BAFTA nominee Gary Lewis (Billy Elliot). 

 Vigil has an 84% critics' rating on Rotten Tomatoes, with Wall Street Journal hailing it as "one of the better thriller series of the year..." and Radio Times including it in their Top 10 of 2021 list, saying, "From the shock death inside the opening 10 minutes of episode one to the thrillingly tense climax in the final instalment, this was a terrifically gripping and propulsive affair that proved a huge hit with the viewing public."
