Princess Elyce is on the verge of marrying the nephew of the unscrupulous King Conrad of a neighboring kingdom when she discovers that Conrad will use her marriage to force her people to work in his mines. In order to fake her own death and escape him, she takes a sleeping potion, planning to awaken on the third day and then travel to Prague to seek help from King Wenceslaus, who rules the Holy Roman Empire. But her plan goes awry: the third day comes without her waking up.
Sir Gerard is convinced by Delia, his sister and Elyce's best friend, to go help the sleeping princess, still slumbering and held captive by King Conrad's guards. He manages to wake her with a kiss, but the princess is not pleased at this rude awakening. Still, he is her only hope of escape. Thus begins their journey to Prague in the dead of winter, hounded on all sides by elements and enemies. The greatest threat may come from within, though, as they desperately fight against their growing feelings for one another.
