Two amateur filmmakers attempt to make a documentary about the legendary underground "phone-work artist" Longmont Potion Castle, who, since 1988, has released sixteen albums of hilariously surreal phone pranks.

A year later, the unpaid camera operator liberates the raw footage and finishes the film.
