Cole is a likeable regular guy. Except that ever since he witnessed a gruesome murder-suicide, things haven't been quite right. His wife left him, he is tormented by hallucinations and his career has nosedived into a blue collar job with a carpet cleaning service. Just when it seems his life has reached bottom, Cole is called out on an all-night cleaning job in an Italianate mansion far from the city. For company he has Henry, the rich, condescending homeowner who seems to take sadistic pleasure in letting Cole think he has just murdered his wife. A reddish stain on the carpet, a knife hacking into baked rabbit, a cell phone that won't stop ringing - does it add up to murder or is Cole losing his last handhold on his fragile sanity?

This is the story of a friendship that changes the course of rock history forever, of the fateful collision of minds between JB and KG that led to the creation of the precedent-shattering band Tenacious D, and of the two heroes' quest to find the fabled Guitar Pick Of Destiny...
