Perhaps more of a sci-fi orientated thriller than a horror, the film starts with six people waking up to find that they've been imprisoned in an elaborate maze of rooms, housed in a giant building that rather resembles pinheads puzzle box.
The six individuals, who comprise of a cop, an escaped criminal, a college student, a social worker, an industrial designer and a mentally ill person, set about trying to navigate their way through the maze of rooms, which all look identical to one another. However, matters become complicated when it is discovered that some of the rooms are booby trapped.
They also discover however, that each one of them possesses a skill that just might enable them to escape from the maze, but as they press on they find that the traps become more and more elaborate and ever increasingly difficult to detect.
The maze of rooms seems to just continue without end, and after being unable to find an exit, suffering from fatigue and without any food or water to sustain them, tensions run high, tempers become frayed, and very soon they start at each other throats.
Overall this is a very good film, the intro scene showing some chap getting "diced" was awesome and really set the tone for the rest of the movie. There's some really great twists in the plot, that keeps you guessing as to who will survive and whether or not any of them will ever make it out alive.
