After several years in India, Sir Guy De Vere (Jack Buchanan) returns to England where he has inherited his ancestral castle. His snobbish relatives, already disgusted by Sir Guy's cheek irreverence (and his insistence upon chumming around with the "common folk"), plot to wrest control of the estate from him. Among his detractors is his beautiful cousin Lady Rowena (Fay Wray), who yearns for the days of Chivalry, when noblemen behaved like noblemen. After several misfire efforts to prove that he can be as chivalrous as the next fellow, Sir Guy is rendered unconscious by a falling suit-of-armor -- and when he awakens, he finds himself back in the 15th century, "when knights were bold." Naturally, all of his relatives have also been thrust back in time, at which point the film becomes a farcical (and tune-filled) derivation of A Connecticut Yankee in King Arthur's Court, with Sir Guy proving that chivalry ain't all it's cracked up to be. When Knights Were Bold was based on a stage play by Douglas Furber and Austin Parker, and was photographed by future Oscar-winner Freddie Young.
