Her arrival is met with suspicion by the sub’s commanders, who try to block her investigation at every turn.
Who knew the Scottish Police Service had oversight even when crimes happen in the middle of the ocean? When a Royal Navy officer (the hard-working Martin Compston) turns up dead of a suspected heroin overdose on a ballistic missile submarine, DCI Amy Silva (Suranne Jones) is sent by helicopter from Glasgow to board the submarine and investigate what happened. Her arrival is met with suspicion by the sub’s commanders, who try to block her investigation at every turn. Back on land, Silva’s police officer and ex-girlfriend is in charge of tracking down links to the crime where the officer was stationed. “Vigil” ratchets up the tension by utilizing the sub’s natural claustrophobic setting to dramatic effect.
