The first film adaptation of Heiberg’s classic play about a superstitious mother, Karen, the elf-maiden Agnete and King Christian IV. Two infants are swapped at birth. Noble-born Elisabeth Munk is found on Elverhøjen (Elves’ Hill) and is brought up as Agnete, a peasant girl, whom all the locals believe to be an elf-maiden. She meets a noble knight, Sir Ebbesen, and the pair fall in love. But Sir Ebbesen is expected to marry a woman of his own noble standing – none other than the girl erroneously brought up as Elisabeth Munk. Suspecting that there is something fishy about the entire affair, King Christian IV sets out for Elves’ Hill to discover the truth of the matter. (stumfilm.dk)
