Video geek Shep uncovers a 135 year old videotape on which mad scientist Artemis Winthrop displays a machine he's invented, which he believes can bridge dimensions. With his buddies, Shep tracks down the machine despite warnings of Winthrop's great-granddaughter, a wiccan named Amelia. Shep restores the machine and while video taping it in action, a horrible accident transforms him into the ultimate tapehead (while unleashing killer bugs from another dimension and a few walking corpses along the way).
