Ep 1. Episode 1

In the first episode of Vigil, we are introduced to the HMS Vigil, a British nuclear submarine that has been on a mission in the North Atlantic. As the crew begins to wind down and prepare for their return to port, they receive a distress signal from a nearby fishing trawler.

Commander Amy Silva, played by Suranne Jones, is in charge of the Vigil and makes the decision to investigate the signal. As they approach the trawler, they discover that something is amiss. The crew is found dead, with one survivor in critical condition.

The survivor, a young woman named Kirsten Longacre, is brought aboard the Vigil for medical attention. However, her presence on the submarine becomes a source of tension among the crew, particularly the weapons officer Lieutenant Commander Mark Prentice, played by Adam James.

As the investigation into what happened on the trawler continues, tensions on the submarine continue to rise. It becomes clear that there are conspiracies and secrets buried deep within the walls of the Vigil.

The episode also introduces us to the larger political landscape surrounding the HMS Vigil. The submarine is carrying sensitive cargo, and there is a race against time to ensure that it reaches its destination safely. As the crew grapples with the events of the day, they must also remain vigilant in the face of potential threats from external forces.

Vigil season 1, episode 1 sets the stage for a gripping drama that explores the inner workings of a highly sensitive organization. The tension is palpable from the opening scene, and the episode leaves the audience on the edge of their seats, eager to see what happens next.
