In their search for clues, the cleaning duo find that their client (now a guitar) had been performing bizarre musical experiments on her computer involving ancient Celtic manuscripts. What follows is an offbeat and humorous journey to locate the one man who can help restore their client's humanity...but he isn't so eager to do so!
