Vigil series two takes to the skies as new cast enlisted
Whereas the first series saw the duo investigate the death of a crew member on board a Royal Navy submarine, the second six-parter will see them take on the British air force.
Following a number of unexplained fatalities at a Scottish military facility, DCI Silva and DI Longacre set out to reveal the cause. But standing in their way are the hostile and closed ranks of the air force.
