However, it wasn’t long before his character suffered a shocking fate.
In scenes that completely took viewers by surprise, Martin’s character Craig Burke – a crew member on the submarine HMS Vigil – died after suffering a supposed drug overdose in the opening five minutes.
While it was ruled that Craig died after snorting heroin, Suranne Jones’ character DCI Silva is determined to discover the real truth.
Martin, known for playing DI Steve Arnott in Line of Duty, is one of the biggest starts in the new series.
Viewers were left completely astonished by Craig’s death, voicing their disbelief online.
Taking to social media, fans voiced their shock and surprise at the early development.
‘He can’t be dead already!’ one said.
‘Well that was a short role for Martin Compston,’ another quipped.
One viewer cried out in their tweet: ‘I swear to god, if you’ve killed off my man I will not be happy!!!’
It’s now up to DCI Silva to discover what really happened to Martin’s character, after heading down into the submarine herself to investigate.
We have so many questions after the first episode, with so much to be uncovered in the forthcoming five episodes.
Suranne and Martin are joined in the cast by the likes of Game of Thrones’ Rose Leslie, who stars as DCI Silva’s partner and fellow copper Kirsten Longacre.
Paterson Joseph of Peep Show also plays submarine commander Newsome alongside Lauren Lyle, Adam James and Stephen Dillane.
Vigil continues on Monday at 9pm on BBC One.
