A brand-new observational documentary series following the exceptional people behind His Majesty's Maritime and Coastguard Agency. With exclusive access and 12 months in the making, we follow the multiple team organisation across the length and breadth of the UK.From daring Search and Rescue helicopter incidents to fatal criminal maritime investigations, as well as survey inspectors examining and detaining fishing trawlers to commercial tankers and the ever-tense 999 mayday operations centre where nail-biting stories playout. We follow this and more as the MCA protects and responds to incidents and accidents on our shores.
