Ana is on her way to visit her new boyfriend when her ex-husband attempts a vicious kidnapping resulting in a car accident. Ana crawls out of the wreckage and walks down the highway towards the nearest town. Gene, an American tourist vacationing in Baja, stops to pick her up. Ana soon finds that her world is not the same. The hotel where she was supposed to meet her boyfriend is in ruins and the people that inhabit it seem more animal like than human. Later that night she has a disturbing nightmare that introduces her to her animal self. She dreams of moths and caterpillars intertwined with human limbs and body parts. She wakes up more confused and shaken, but her journey continues.
