Written and created by BAFTA-nominated writer Tom Edge (The Crown), the six-part series will follow DCI Amy Silva (Jones) as she investigates two mysterious events, which bring the police into conflict with the Navy and the British security services.
A synopsis says: "The mysterious disappearance of a Scottish fishing trawler and a death on-board a Trident nuclear submarine bring the police into conflict with the Navy and British security services.
"DCI Amy Silva (Suranne Jones) leads an investigation on land and at sea into a conspiracy that threatens the very heart of Britain's nuclear deterrent."
Along with Compston, who you'll recognise from Line of Duty, Jones will be joined by the likes of Anjli Mohindra (Bodyguard), Paterson Joseph (Noughts + Crosses), Connor Swindells (Sex Education), Adam James (Doctor Foster), Gary Lewis (Outlander), Rose Leslie (Game of Thrones) and Stephen Dillane (Game of Thrones).
A first look from the BBC shows Jones in action as DCI Silva, as production resumed earlier this week near Glasgow after being 'paused in line with Covid-19 guidelines'.
Along with writer Tom Edge, several episodes have also been written by Ed McDonald (The End Of The F***ing World) and Chandni Lakhani (Dublin Murders).
Suranne Jones said in a statement earlier this year: "Tom Edge has created a thrill of a story, set in a world I knew nothing about.
"The cast and crew World Productions have put together to tell this story is so exciting. 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 and I can't wait to start filming."
Edge added: "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."
While there's no release date just yet, we're hoping if filming is underway again we won't have to wait too long before it's on screens.
