Three hundred years ago, Frost Giants cursed the dragons, stripping them of their forms. Edmund, the only one who can still transform, seeks to break the curse through an arranged marriage—only to be publicly humiliated. King Carn offers Princess Alicia instead. From mutual disdain, they grow to love each other. Together they battle the bastard prince James and Frost Prince Haakon, who seek to resurrect the Frost King. In the final clash, Edmund transforms into a black dragon and defeats the Frost King. Their love shatters the curse, and dragons soar again.
