Jennifer's famous spelunking father dies and leaves her with an unusual burden: a man. The Mexican police are certain this strange man is her issue to deal with.

At the center of her dissolving sanity is the black-haired man named Keth.

Torn over a promise he made to Jennifer's father, Keth desires nothing more than to kill Jennifer and be free.

The mysterious man who had so attracted her in the beginning begins to tell his tale and she realizes he is either mad or her comfortable existence hides truths she cannot grasp. Together they will answer each other's questions but the process leaves a trail of death and destruction when other, even more insane, forces intervene.
