Nietzsche's Kisses is the narrative of Friedrich Nietzsche's last mad night on earth. Locked in a small room on the top floor of what would become The Nietzsche Archives in Weimar, one of the most radical and influential of nineteenth-century German philosophers hovers between dream and wakefulness, memory and hallucination, the first person, second, and third, past and present, reliving his brief love affair with feminist Lou Andreas-Salomé, his stormy association with Richard Wagner, and his conflicted relationship with Elisabeth Förster-Nietzsche, his radically anti-Semitic sister.
