Season one of hit BBC show Vigil concludes tonight, with plenty of questions likely to be answered.

A cliffhanger episode last Sunday saw lead character DCI Amy Silva – played by Suranne Jones – left to drown in a torpedo tube.

But many fans will now fear she doesn’t make it after teaser pictures from the final programme – on tonight at 9pm – showed one of the officers who shoved her into the tube sitting at a press conference.

The BBC One drama has been made by the same production company behind Line Of Duty and Bodyguard. After first being announced by the broadcaster in 2020, Vigil attracted an audience of millions to its first two episodes.

It centres on the mysterious disappearance of a Scottish fishing trawler and a death on board submarine HMS Vigil, which bring the police into conflict with the Navy and British security services.

The story of the missing trawler is loosely based on the sinking of the Antares on the Clyde in 1990, which was pulled under by a nuclear submarine with the loss of all four crew on board.

The submarine on the show is based on the UK’s Trident fleet at Faslane, near Helensburgh.

Vigil was shot in Scotland and features a fictitious naval base along with peace camp protesters nearby, like the real-life one on the road to Faslane.

The six-part series – which also stars Martin Compston, Lorne MacFadyen and Stephen Dillane – was created by Bafta-nominated writer Tom Edge.

Where and when to watch?

The sixth and final episode of Vigil will be on our screen tonight, September 26 at 9pm.

If you miss it, you can catch up on the episode, as well as all other episodes in the serious, on BBC iPlayer after the show finishes this evening.

Will there be a season 2?

Vigil was billed a mini-series, meaning all the loose ends are likely to be tidied up during tonight's finale.

However, a TV insider previously told The Sun that talks of another season are likely to progress after the massive success of this run.

BBC bosses are keen to maintain momentum after it became the most-watched show on the weekend of the first episode - with 5.6million tuning in.

It is uncertain whether Suranne Jones would return or when the show would be filmed and aired.
