Based on the book O Fantástico Mistério de Feiurinha, the story combines real world and fantasy, dream and determination, with a surprising end, even for a fairy tale. The movie shows the fight of the fairy tale characters, now adults, who come together to recover the fable of the Little Ugly Princess, a beautiful Princess with a strange name, which only makes sense for those who know her story. The problem is that children and adults have forgotten the story of the Little Ugly Princess, which is as wonderful as other major fables for children. Cinderella brings together other fairy tale characters to meet the writer who keeps, lost in a small notebook, the Little Ugly Princess story.
Elias sees his world threatened when his ex-wife, one recovering junkie, asks for the guard of their son. Fito is in desperation for losing his father because of Elias. Isis, who hides in a vagabond hotel, can be the salvation for Fito and Elias.
