For whatever reason, this has long been one of my top 5 MST3K episodes. Well, that reason is primarily Zap Rowsdower, the burly, mustachioed, Canadian-tuxedo'ed co-star of the movie. Paired with the weiniest kid to ever star in a movie, it's a match made in cinema glory.
The plot is pretty... terrible. Something about a cult chasing around looking for a map so they can raise an ancient city or something (it's sort of confusing). A young guy who's dad was killed 7 years back while doing archaeological work outside of Alberta, I think. A lost city of Atlantis in Canada.
I dunno. You kind of need to see it for yourself.
