This quite a good simple thriller from Spain (English subtitles). Rosa, (Ana de Armas, Knock Knock, War Dogs), a young Cuban immigrant working an unfulfilled life in housekeeping in a hotel, tired after a long shift where she is being hassled by an ex boyfriend on the phone who still expects to sleep with her, as well as dealing with her boss who enjoys the power he has over her on the job, plays a voicemail on her phone from a call she missed as her phone isn't working too well. She has gotten to the final round for I assume a James Bond opening credits dance role that we saw as this movie's opening credits. She may finally be able to get out the depressive existence she's in. However her sister has also left a message that the washing machine isn't working, so since she only has one outfit she's got to go to the 24 hour laundrymat down a long alleyway from her house. We the viewer know other women have been being killed in this alleyway.
The movie changes what it is for last ten minutes or so, (some DVD versions front cover image spoil this for the viewer) which I thought wasn't necessary as it was a great survival thriller on its own anyway, although the special effects at this point are brilliant. The last minute or so of the movie though didn't really make sense (see my comment). But that didn't detract from the movie overall, which was really enjoyable.
