Psychiatrist Martin Kirsch takes the case, little suspecting that this will be his last. As he searches for the truth about 'the Einstein Girl', professional fascination turns to reckless love. His investigations lead him to a remote corner of Serbia via a psychiatric hospital in Zürich. There the inheritor of Einstein's genius -- his youngest son, Eduard -- is writing a book that will destroy his illustrious father and, in the process, change the world.
