Dr. David Denton develops a virtual reality EEG machine that makes it possible for the observer to be able to experience the exact activities, feelings, and thoughts of the subject of the test. Certain patients or victims of violent crimes are those who most often undergo this unusual examination. The technology is stolen by one of the doctoras technicians. He uses it for recordings during intimate relations, which can be played back reproducing the same experience for whomever uses this device. He successfully markets this and begins to make a great income. However, this technician inadvertently scans the disc of a patient who died during the recording, undergoes a most unusual experience, and pays for his crime.
