Spainish low cost thriller movie. The story tell that three sisters entering a senator's house, trying to steal the money he got from the bribe, but once they entered the house, they began to hear strange calls from the basement. . . . The movie is better than the imagination. The exorcism ritual part is the climax of the whole film, and it is also the best part. Although some of the plots are old-fashioned, but they are eye-catching. Although the blood stasis and convulsions are normal , the relationship and details of the characters are not described good enough, but the atmosphere and the climax are good, with a small turning point.
