Thriller / crime movie. 9 people are kidnapped and locked up in one place. The kidnapper will kill one of them every 10 minutes until they find the reason they are there and the reason their lives are interconnected. Very nice and clever idea although not original since there are others with a similar mystery that must be solved against time, the top series of mystery / crime movies was probably SAW (although it also had a gore / splatter there). However, despite the suspense and mystery it was not intense enough, it was shot almost entirely in one room and the ending was purely disappointing. Nevertheless, it is worth a watch and recommended to all fans of the genre.
