A mysterious, wealthy boss and his dysfunctional group of twenty-somethings build a secret time machine while the NSA surveils the affair. But when the group sends their first victim traveler forward, he comes back with news that someone is murdering them all, after which the story turns into a teen slashfest with bad acting, worse writing, and no interesting turns. Nevertheless, the movie does an almost perfect job when it comes to creating a single, nonparadoxical timeline.
