It's a film that makes it you watch it till the end. A simple enough idea, broken apart into pieces and put together in a productive way of storytelling. The synopsis is as it says, about a small psychology class & their curious, inventive teacher who puts his class inside of a specific scenario of unknown motives & origins. The viewer gets pieces of the classes back story as the film flashes back & forth from their previous class sessions & their current crisis situation filling us in on what motivates the instructor. It's not until the film's end that the dark truth becomes clear. One can label it as a twist of sorts, but I prefer to think of it as the unknown variable being unveiled. It's a very short film of 69 minutes before credits although it doesn't seem to suffer from it's lack of length. It's acted & filmed well enough considering it's budget not too mention it's little known director doing a good job working with the available sparse resources making this little thriller earn a 5.7/10 from me. I'm not saying to bend over backwards to find it, but rather to check it out if you happen to run into it.
