Poison for the Fairies

Flavia (Elsa Maria Gutierrez) is a wealthy, lonely schoolgirl in 1965 Mexico City, and she takes up with Veronica (Ana Patricia Rojo), an orphan who talks constantly about witchcraft. Veronica tells her she is a real witch and makes her an assistant, and the games they play get more serious, with Veronica asking for more each time. Carlos Enrique Taboada keeps the film on these two girls, one who wants a friend and one who wants to be obeyed.
