King Hans needs to produce an heir. Though he has searched the lands, he can find no woman who satisfies him. He suspects deep down that the problem is with him but can find no solution to his malady. 

Hans is starting to despair when he hears of the sorceress ice queen, Ilsa, purported to be the most beautiful woman in the land. He travels her to her, and she does something completely unexpected—she turns Hans into a woman. 

At first furious, Hans starts to realize that perhaps this was what he needed all along to feel like himself. If he could, Hans would stay with Ilsa forever, relishing in the delightful things she does to him and basking in their growing affections. However, matters in his kingdom are not well, and Hans has to choose between his kingdom and staying a woman. 

It's the hardest choice he ever has to make.
