Based on a true story, the successful playwright Nino Haratischwili poses the question of authenticity in her first novel. The book "Die Eiszeit" by Jeanne Saré becomes a major bestseller in the 1970s, particularly in feminist circles. The hate-filled book of the teenage suicide victim Saré inspires several readers to take their own lives. Now, in the present day, an art scholar in Paris embarks on a quest to find Saré. What connection does the book's publisher, a misogynistic older man, have with Saré? Who was Jeanne Saré really? Why are there no testimonies? And how could the book have such an impact? Nino Haratischwili skillfully intertwines multiple narrative threads in this novel and describes in a dizzying manner the significance of the real and the unreal for social life.
