After one too many tokes, a trio of potheads gets trapped inside a mystical and malevolent bong that gets stronger and stronger with each hit taken from it. Stuck in the bong's surreal, trippy realm, the stoners' only hope lies with their geeky roommate, provided he can resist the weed's wily charms. David Weidoff, John Patrick Jordan, Mitch Eakins, and (of course) Tommy Chong star. 86 min. Widescreen; Soundtrack: English; featurettes; theatrical trailers.
