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.
Unfortunately the movie Ruma Elsa is not yet available on HBO Max.
