Derek Amato is truly one in a billion. He is possibly the only person in the world to have acquired musical ability after a traumatic brain injury. A severe concussion left him with the ability to play piano, an instrument he had never played before. He now plays professionally and earns his living as a musician.

Now, the music never stops. He sees it constantly streaming in front of his eyes in the form of black and white squares that compel him to play. Derek journeys to the Mayo Clinic to meet with one of the world's top neurologists to try and find a way to control the incessant stream of music: an incredible gift that is also his curse.
