A bump on the head sends Hank Martin, a 1912 mechanic, to Arthurian Britain in 528 A.D., where he is befriended by Sir Sagramore le Desirous and gains influence through his clever use of technology. Hank and Alisande, the King's niece, fall in love at first sight, which draws the jealousy of her fiancé, Sir Lancelot.
