My one line summary is a reworking of the tag line "The less you know, the safer you are". Reading the original synopsis on IMDB gives too much away. If you haven't read it - don't. Just RUN to the store and rent this video. Be like me and don't read the synopsis on the box either. Just take my word for it and that of the anonymous author of the very well written comments that precede mine. This is a GREAT movie. It's witty, falling down funny, sad as blazes, suspenseful, and exciting. Stewart and Williams are dynamite together.
