Devoured (2012)

Lourdes is a young woman who works at night cleaning a restaurant. All the money she makes is for her son that lives in her hometown with her mother. We know very little about Lourdes son, only that he is sick and Lourdes is working every night and sending money to help her son and find a cure for his illness. Suddenly, Lourdes starts seeing visions in the restaurant where she works and in her little apartment. These visions are of her evil co-workers and her son. This stresses Lourdes to the point where she begins asking herself, "Does someone want to hurt me?", and, "Is any of this really happening?"
