Estee, a seasoned curator for a small Massachusetts auction house, makes an astonishing find: the original manuscript of Sylvia Plath’s semi-autobiographical novel, THE BELL JAR, written by hand in her journals 55 years earlier. Vetting the document, Estee will discover she’s connected to Plath’s legacy in an unexpected way. Plath’s psychiatrist, Dr. Ruth Barnhouse, treats Plath during the dark days she spends at McLean Hospital following a suicide attempt, and eventually helps set the talented poet and writer on a path toward literary greatness. Poet Boston Rhodes, a malicious literary rival, pushes Plath to write about her experiences at McLean, tipping her into a fatal spiral of madness and ultimately forging her legacy.
