If you’re already feeling the loss of Line of Duty after the series finale, then Vigil is just the thing to get your teeth into.

Starring Martin Compston and Suranne Jones, it centres on a murder investigation aboard a creepy submarine in the deep sea, spanning the Navy and the British security services in its wide-ranging search for answers.

We’re so excited to get stuck in to Vigil – here’s everything you need to know about its plot, cast and when it’s on TV.

What is Vigil about?

The mysterious disappearance of a Scottish fishing trawler and a death aboard Trident nuclear submarine HMS Vigil align for an investigation that delves deeper than detectives could have realised.

DCI Amy Silva is nominated to lead the police investigation into the submarine death, a daunting prospect as she is lowered into the waters to join the remaining crew who are still out at sea.

Her detective work both at sea and on land pits the police against the Navy and security services to uncover a conspiracy that threatens the very heart of Britain’s nuclear deterrent.

Writer Tom Edge said: “The ‘Continuous At Sea Deterrent’, better known as ‘Trident’, has been a contentious part of national life for half a century now, a stock of nuclear missiles kept hundreds of feet below the sea surface.

“But this world has rarely been explored on screen. I can’t wait to take a BBC One audience down with us, into the pitch-black icy waters of the unseen Atlantic, where tomorrow’s geopolitical struggles are already being played out.”

Who is in the cast?

Starring as DCI Amy Silva is Suranne Jones, who said: “Tom Edge has created a thrill of a story, set in a world I knew nothing about.

“Amy Silva is a brilliantly complex character, thrown into a highly charged situation where her authority is weakened.

“We watch as she navigates her own personal trauma and loss, all at a time when she’s questioning her relationships and life choices. It feels fresh and relevant.”

Jones is best known for her roles in Doctor Foster, Gentleman Jack and Coronation Street.

Also look out for Connor Swindells (Sex Education, Jamestown), Adam James (Belgravia, Doctor Foster), and Gary Lewis (His Dark Materials, Billy Elliot).

The series started filming early in 2020, but was of course shut down by the coronavirus pandemic.

It resumed filming in the summer and is expected as a six-part drama on BBC One later this year.
