this could have be your run of the mill erotic thriller with the tired plot of lonely couple take in drifter and drifter have affair with woman and etc . however with superb acting by the entire cast and good writing and direction this go beyond the genre . after schub appear in the last part and the movie get even well . denoument come fast and furious . i keep expect it to lapse into cliche and but it never do . i do not understand the last scene with alonso and but this be a must see sleeper .
