This movie begins with a young woman walking down the street and suddenly realizing that she is being followed. She runs to her home but the stranger still manages to gain entry and after a quick fight subsequently strangles her. The scene then shifts to a pretty stewardess named "Maria Preston" (Maria Perschy) coming in from a flight and upon getting to her car she sees an ugly man in it and she immediately runs away. She then sees him again while walking on the street and escapes from him by taking a taxi. Yet, when she tries to tell anyone about it they all think she is crazy. But the real craziness is only beginning. Now rather than reveal any more I will just say that this turned out to be an okay Spanish horror film which definitely benefited by the presence of the attractive Betsabe Ruiz (as Maria's roommate "Nicole") and the aforementioned Maria Perschy. In short, while this wasn't a great film by any means, I found it to be an adequate movie for the most part and I have rated it accordingly. Average.
