English ships are being rammed and sunk by a castle-like ship of "The King of the Sea", a secret ally of Prince John. Robin Hood sails with his Merrie Men in pursuit and secretly boards, but is captured and made a galley slave. He breaks free, bolts the door, and orders the slaves to row - so the ship is beached. Rescued by his Merrie Men, they dump "The King of the Sea" on Prince John's doorstep!; At Camelot, Knights of the Round Table hear Galahad and Lancelot boast of beating giants and dragons. But Guinevere says a never-done task would be to make the Silent Knight speak!.. In the Forest Perilous, Squire Brian becomes the Silent Knight, eludes Sir Edwin's spy, dodges Galahad's lance and sword, then tumbles Sir Lancelot into a river... The knights are mocked in Camelot, but Brian wonders when they'll meet again.; Jon is glum as he recovers from an ordeal at sea. No one would believe his tale... Fishing alone, he was caught in a storm and driven westward for weeks to a new land (North America). He rescued a girl from a "feather-helmeted" villain, and was made chief to fight for the tribe. In an attack, Jon rallied Indians, drove back the enemy, and captured the villain. Then left, sailing eastward... Now he's back, silent, but knowing someday the tale can be told.
