In the late 1800's, Franz Ferdinand, heir to the Austro-Hungarian empire, falls for Sophie Chotek, a Czech countess. He's already a problem to the Crown because of his political ideas. In addition, a love affair with someone not of royal blood breaches protocol. The Crown allows the union only after the couple agrees to a morganatic marriage. Franz doesn't seem to care about the protocols of the time, provoking the emperor to further neutralize him by demoting him to inspector general of the army. In June 1914, fearing for his safety, Sophie seeks permission to accompany Franz to Sarajevo; protocol dictates that no army troops attend Franz while she is present. An assassin strikes. Their deaths spark World War I.
