Vasilisa the Wise was a sorceress, enchanted by her father, Koschei the Deathless, for having surpassed him in the art of witchcraft. Forced to spend three years in a frog's skin for disobeying Koschei, she was desperately waiting for a prince to come and save her from an evil curse. And she almost succeeded to break evil spells - just like an old witch once told her.

One day Prince Ivan shot his arrow into a swamp. When he went there to find it, he found a frog holding the arrow in its mouth - not knowing it was Vasilisa waiting for her fate to come. As earlier Ivan promised his father to marry whoever lives at the place where his arrow lands, he kept his bargain and treated the frog as if she were a princess.

As time went by she knew a way to transform into human form by shedding the frog skin and becoming beautiful girl - but only during a day. One day Ivan found out his wife secret. Willing to finally break the curse, he's waited for the right moment, stole the Frog Princess' shedded skin and burnt it, to her dismay. Had the prince been patient, his wife would have been freed but instead she stuck in-between: half-woman, half-frog. Not all the fairy tales end well, you know...
