Composer Peter Els opens the door one evening to find the police on his doorstep. His amateur science lab – the latest experiment in his lifelong attempt to find music in the most surprising places – has aroused the suspicions of Homeland Security. Panicked by the raid, Els turns fugitive. As an internet-fuelled hysteria erupts, Els – the ‘Bioterrorist Bach’ – pays a final visit to the people he loves, those who shaped his musical journey. Together, they hatch a plan to turn this disastrous collision with state security into a work that will reawaken a nationwide audience to the glorious sounds and symphonies that lie hidden all around them.
