The brand new six-part series sees the action move from the rails to the open water, as a Belfast-to-Liverpool passenger ferry becomes the target of a potentially deadly hack-attack. With the crew desperately trying to hide the extent of the threat from the passengers, the ferry’s second engineer Johnny must work with the National Cyber Security Centre’s new technical director, Bo, to try and fight back. But as the tide turns, secrets surface and fear floods the decks; it isn’t long before those on land are all at sea too…
