Adapted from a Vietnamese fairy tale, Tam Cam: The Untold Story is similar in narrative structure to Cinderella: kind and beautiful Tam is ill-treated by her stepmother and stepsister, but a fairy guardian watches over her. A demon pretending to be a faithful servant to the king waits for an opportunity to become human. The intrepid prince is asked to marry politically but he declares that he is going to marry the woman whose feet fit the silk shoes, hoping it's Tam, whom he met by chance.
