Eivor Engelbrektsson

Adolph Turesson is a mild-mannered, meek college professor whose faint-heart isn't impressing the fair-lady he secretly loves, the golden-haired Britta Larsson. Attending a lecture, he witnesses the attention paid to his lady-love by other faculty members, and falls to sleep. He dreams of the olden days and the knights, and the comely ladies of the court over whom they fought. His dream also gives all the cast the change to play a second role. Upon awakening, he proposes to Britta. (imdb)
