Anadina.

Just outside her apartment, Ana finds Dina, a naked, mysterious and confused young woman. Ana invites Dina in and calls a couple of persons so that they can meet her. Pamela and Raymundo, human traffickers, show up to negotiate the buying of Dina, who claims that she comes from the future and that she is actually on a mission to investigate how far human evil has grown in Mexico by the year 2015. The young woman provokes an unsolvable dispute between the traffickers, who end up dead.
