Like the title says, you've probably never heard of this under-marketed suspense thriller with Kim Basinger (long before Vicki Vale), Nick Mancuso, and Charlton Heston. It sets up its premise quickly, with a search for a missing man that turns into a tense quest for gold in a played-out gold mine. Nothing terribly thought-provoking; it's not War and Peace, but it's a fun, claustrophobic little thriller with a plot-twist that maybe isn't the most original in the world, but the cinematography is well done and might have you jumping at shadows by the end.
