Navy film intended to give an insight into the lives of the officers and men onboard the County Class guided-missile destroyer HMS Norfolk (D.21).
The film begins with 'call the hands' and scenes of sailors getting up, washing, having breakfast and mopping decks. Scenes on the bridge, in the ship's laundry, in machinery spaces and in the galley are shown before the ship begins preparation for gunnery and missile firings. The automatic loading mechanism for the ship's Sea Slug missile system is shown delivering a missile to the launcher before the weapon is fired. Men inside the 4.5-inch gun turret load shells into the breach, and rapid firing is shown from an exterior view. Two officers discuss a technical fault in the Wessex helicopter and the ship then anchors off Monte Carlo. The Captain makes his official calls to local dignitaries while sailors relax. Back at sea the ship replenishes from the Royal Fleet Auxiliary ship RFA Tarbatness (A.345) and the ship's accounts are discussed. The ship prepares to fire an Exocet missile, which is shown launching, in flight and impacting on a target ship.
