The Killing Room (Movie Watch)

Four volunteers sign up for what initially appears to be a typical paid research study, only to discover that they've unwittingly become involved with a classified government program that was said to have been terminated nearly two decades ago. As the study gets underway, the group is presented with a series of questions, & given a finite window of time in which each individual member must submit a unique numerical answer. At first, the participants all assume that the subject who gives the most obviously incorrect answer will be removed from the experiment, though it doesn't take long for the group to realize that the correct answer isn't always the answer that the researchers are looking for.
