9 people are kidnapped and tied up and told that unless they discover why they are there one of them will be killed every 10 minutes. It's a reasonably familiar tale but it's fun watching them try and discover why they are there.
The film features the usual eclectic mix, drug dealer, cops, priest etc. These type of films rely heavily on having interesting characters to watch and although there are plenty of clichés on show, I found the characters pretty entertaining. There isn't any SAW like gore in this film and most of the violence is off screen. I was a bit surprised to see Melissa Joan Hart from Sabrina the Teenage Witch fame in this and she is pretty good in this. The rest of the cast also put in decent believable performances.
As the captives piece together the puzzle and the numbers deplete it all winds down a bit to a slightly disappointing climax. The end scene being one of the most abrupt and unexplained I've ever seen.
Overall I found this a fairly enjoyable if limited thriller and probably wouldn't rush to watch it again.
