An unpaid camera operator is left to finish the film a bumbling pair of filmmakers attempt to make about the greatest anonymous phone-work artist of all time -Longmont Potion Castle. The Banksy of phone-work, Longmont Potion Castle’s oeuvre is probably best described by executive producer Rainn Wilson as “a sublime work of art: as if Salvador Dali moved to suburban Denver, got stoned and made prank phone calls.” For over 30 years, Longmont Potion Castle has been releasing phone-art insanity to his rabid fan base that include such luminaries as Queens of the Stone Age, Jimmy Eat World, Deer Tick, Steve Aoki and a host of other entertainers and musicians who turn to Longmont Potion Castle for laughs and inspiration. Featuring interviews with Rainn Wilson, Andrew Bujalski, P***ed Jeans, Municipal Waste, the owners of NBS Electronics as well as the Twist and Shout record store, Pig Destroyer, Weyes Blood, Cattle Decapitation, Pinback, and a variety of hardcore fans, “Where in the Hell is the Lavender House? The Longmont Potion Castle story” peeks behind the curtain of America's underground phone-work king, and documents a film doomed to fail from the beginning.
