Crown Prince Rudolf is tormented by dark obsessions, fixated by the idea of his own death. He cannot find solace in friends and family, except for one person: the young and beautiful Baroness Mary Vetsera. She too, shares his morbid interests. Stifled by the oppressive conventions and pageantry of the Austro-Hungarian court, Rudolf and Mary start meeting in secret. As fervent desire combines with a fascination for death, what begins as a clandestine love affair hurtles towards tragedy.
