OH MAN I rented this years and years ago when it hit VHS.
SUrprisingly entertaing for some weird, no-budget attempt at....something.
It had something to do with some guy trying to dump a chemical into the water supply of the city to "wake people up" out of some kind of mind control Matrix thing.
That's basically what it is - The Matrix, but 10 years earlier, and with a healthy dose of chaos theory instead of hamfisted religious symbolism (the scriptwriter/director/editor/actor/etc. Chris Shaw was a mathematics professor). Shaw didn't do anything else in film for the next 20 years.
