1906, Vienna. Franz Lobheiner is a Second Lieutenant with the Austrian Army, a position that includes the "expectation" to attend high society functions, a ball where he met and subsequently began an affair with married Baroness Helena Eggersdorf which has thus far lasted one year. But with she needing to sneak away and double and triple check to ensure she has not been followed in their liaisons at his apartment in those infrequent times when she is able, she having a key to let herself in, Franz is beginning to tire of the affair. At the same time, he begins to see Christine Weiring, the innocent daughter of the opera's cellist, solely as a fourth required for double dates between his fellow lieutenant Theo Kaiser and Theo's girlfriend, Christine's cousin Mitzie Schlager. What starts out purely as an awkward obligation for both Christine and Franz turns into the purest of love for both. While Christine already being unofficially engaged to struggling composer Joseph Binder causes a minor inconvenience, it is Franz's affair with the Baroness that causes the major obstacle to a Christine/Franz happy ending in the Baroness not giving up Franz without a fight as she thought that their love was a forever kind, and the Baron not taking her having an affair, if he were ever to discover such, lying down in its betrayal solely against such an important person as himself.—Huggo
