On a Royal Navy submarine, we get to have a glimpse at what life is like beneath the sea. The crew live in extremely close quarters and there is barely enough space for a camera. In this episode, the arrival of a new captain coincides with a troubling encounter when Russian warships and submarines foray into British-patrolled waters.

For the first time cameras have been given access on board a hunter-killer submarine on live operations. Submarine: Life Under the Waves goes on board HMS Trenchant, a nuclear submarine, on its four month tour of duty to the mid-Atlantic to uncover the reality of life at sea.
