Mignon: Noble born Mignon is stolen by a band of gypsies as a child. Her mother dies from grief and her father, unhinged by the double blow, gives up his ancestral home for the roaming life of a minstrel wandering from place to place in search of his child. Ill-treated by the gypsies in time she is rescued by traveling student Guglielno, with whom she falls in love. But he is enamored by the seductive actress Filina. Events come to a climax at a castle where all the participants meet, and drastic actions lead to near fatal consequences until all is resolved happily.
