The year is 1853, and 16-year-old Elisabeth 'Sisi' of Bavaria has been very clear - she will wait for the sweeping, head-over-heels kind of love the poets speak of or she will have no love at all. It is not her fault Mother refuses to listen. After all, just because her older sister Helene has chosen the line of duty and is preparing to marry Emperor Franz of Austria does not mean Sisi also needs to subject herself to such a passionless, regimented existence.

Meanwhile, in Austria, the Emperor is recovering from an assassination attempt that left him wounded and scared. In a bid to keep the peace, Franz has recommitted himself to his imperial duties - and promised to romance the pliant Bavarian princess, Helene.

But when Sisi and Franz meet unexpectedly in the palace gardens, their connection cannot be denied. And as their illicit conversations turn into something more, they must soon choose between the expectations of the court and the burning desires of their hearts...
