The latest BBC One drama Vigil follows a police investigation into a mysterious death aboard a nuclear submarine.
The six-part series is written and created by BAFTA-nominated writer Tom Edge and has a cast of stellar acting talent attached.
The series was filmed in Scotland and follows the death of a crew member onboard the Trident nuclear submarine HMS Vigil, while the submarine is still in operation as the UK’s nuclear deterrent.
What’s it about?
The series blurb on the BBC website reads: “When a crew member is found dead on board the Trident nuclear submarine HMS Vigil, police in Scotland are called in to investigate.
“The catch? The UK’s nuclear deterrent must remain unbroken, so the submarine stays on patrol and Detective Chief Inspector Amy Silva must go aboard to begin an investigation.
“Although the death was written off as an accidental overdose, Amy suspects foul play.
“But when the crew close ranks in the face of Amy’s questioning, a new threat overshadows her inquiry.”
