Under the auspicious name "Magical Mystery" the Berlin techno label BummBumm Records wants to go on a rave tour. Karl Schmidt aka Charly himself was once an aspiring artist on the scene, until he retired after a nervous breakdown five years ago. Since then he lives in a supervised withdrawal WG in Hamburg. Now, as a driver and custodian for the party-loving DJs and their producers, he becomes part of "Magical Mystery", trying to lead a self-determined life after years of patronizing and well-intentioned advice.
