Full title reads: "DRAKE SAILS AGAIN - The 'Golden Hind' once more at Plymouth Hoe."
Several shots of the replica of the 'Golden Hind', Admiral Drake's famous ship, but half the size of the original, with sailors in period costume sailing on it at Plymouth Harbour.
Several shots of the navy exercise - destroyer attacks a submarine seen on the other side of harbour - exchanged torpedoes and gun fire. Men are seen on board destroyer operating a big gun and firing at submarine. Submarine sinks slowly - presumably being hit.
