Four young college students form an experimental group working in controlling dreams through the use of a new form of Transcendental Meditation. They grow to be very close; two are lovers, one is universally despised by the other three, but all four are inextricably linked through their common "dream" adventures in which they interact during their sleep. At a crucial point in their research, the project leader (a professor of paranormal studies) dies, leaving the students to try to further their research on their own. Unfortunately, they don't know what they're doing and they abandon themselves to the temptations of their own fantasies....until one of the students tries to *kill* the others in the dreams.
