The Crystal Tunnel opens with some artful special effects. Close-ups of mineral crystals start swirling around in a dizzying effect that segues into a voice-over by Grant Wood, who is comatose. Grant is a poor-little-rich-boy who was orphaned at the tender age of eight, and left with a Malibu mansion and a multi-million-dollar trust fund. He is jaded and unhappy. While rough-housing on the cliffs, he and his friends (this term is used loosely) spy upon a young couple getting it on, and Grant takes a tumble which leaves him a vegetable. Flashbacks reveal his pathetic relationships with hustlers, drug addicts and gold diggers.

Grant's drug of choice, both in and out of the bedroom, is crystal meth. Tony Cummings pays a sickbed visit to Grant and recaps their meeting. Cummings is having a hotel rendezvous with Spike and, in the middle of getting fucked, needs to step out for a cigarette. He happens upon Grant, who has just left his room with pot-smoking and beer-drinking Sonny Markham and Chip Noll. A mutual interest in speed takes Cummings and Grant back to the room with Spike, and the three are joined by Markham and Noll for the tape's finest scene. Other flashbacks reveal the dark sides of both Grant and his co-stars. The tape culminates in a bitchy reunion that pits everyone against each other and drives poor comatose Grant over the edge. A public service, anti-crystal meth message is delivered by the cast as a postscript. Pre-nom the script, written by Donald Von Wiedenman; Tony Cummings for Best Supporting Actor; and the aforementioned group scene for Best Group Scene.
