If you don't mind an ambiguous and crappy ending, then you might enjoy this low budget attempt at psycho / time-travel / cultdom infiltration. The end is first surprising, then infuriating. Like a selfish lover who teases you to the brink of a mild yet satisfying orgasm, and leaves you hanging to go listen to bad music...
