Returning to work for his mentor, a young doctor at a hospital finds that his mentor has turned his studies of a dangerous disease into reality by trapping everyone inside and begins slaughtering them all one-by-one for his study forcing them to fight him off to escape alive.
For the most part, this one wasn't all that impressive an effort. Among the many problems here is the fact that this one really doesn't have much of anything to do with being a horror effort. The first half of this one is an utterly bland and paltry soap opera about the returning doctor to the hospital and what's going on with the different experiments they're conducting behind the scenes which is not interesting in the slightest, and when added together with the lame treatment with the patients or their own past romance coming back to the forefront just isn't that effective to start the film off. It's just so dull and so far removed from what's supposed to be a horror effort during these moments that it takes even longer than it really should for something to start happening which means that there's a rather low amount of suspense or even kills inside this for a large part of the film. Even some of the later scenes aren't any better, as this one introduces the lame subplot about the suicidal patient that doesn't mean anything and the rampaging killer motif is dropped about ten minutes after it's introduced which renders the entire purpose for its inclusion meaningless by being disposed of quite easily, and once it showcases the struggle in the final half away from the serial killer trope where it focuses more the two being trapped together with the mad scientist route there's just a rather lame and useless thriller style angle being played out with the doctor teasing them and bringing them into his hold before having to fight their way out of it is a rather lame finish to this which ends this on a rather distressing and disappointing note without a whole lot of horror happening throughout this one. These here really hold this one back even though it does have some decent points. The main thing to like here is the featured stalking in the hospital done by the killer who's on the loose, and the impact of the killer stalking the long dark hallways in the hospital and cornering victims in the small, confined rooms makes for a somewhat chilling experience, especially down in the basement where they try to find a hiding space and come upon the true point of the whole exercise as it really interjects some actual action in the matter. That it's helped along with the fine look of the killer who's somewhat imposing, and the kills do provide some nice gore as well which makes for a film highlight. The concept behind the finale is certainly chilling on a whole, even though it doesn't work, and overall makes for a few decent parts to like about this one even though it doesn't work well enough to overcome the positives.
