The boyish, temperamental chemistry student Elsa Kassel disapproves of her mother and sisters running after men, but when she hears that she's referred to as "ugly Elsa", she takes on a transformation. The new, charming Elsa tests her attractiveness on men and causes confusion all the way to her mother's new groom, Professor Harjula.
