Many Lives

A childless farmer and his wife seek the assistance of a witch to grant them their greatest wish, and in the bargain she transforms a tiny barn kitten into a human child. But, as with all deals with the arcane, this one comes at a cost: the girl must receive a kiss from a true love by her 16th birthday or return to her original form forever.

It seems simple enough, until the girl's true love refuses her his kiss.
