First half of movie: Christopher Walken and friends develop a device to record and play back stimuli to / from the human brain. Note that this was released over ten years before Strange Days and one year before William Gibson's first book.

Second half of movie: Cow-orker dies while connected to brain-VCR thingy. The Man takes the tape for military research. Christopher Walken decides that his life's goal is now to watch that tape.

All in all a movie well ahead of its time. Often underrated (though most DVD stores seem to burn through a lot of stock).
