In 1964, four remarkable young women at a prestigious university became the subjects of parapsychology experiments by a visionary scientist. On the cusp of a historic breakthrough, the women mysteriously vanished and the program was erased from history. Decades later, Riley Bell accepts a caretaker job for an elderly widow named Betty. Riley steps into a home that is frozen in another era --- no microwaves, televisions or cell phones, and Betty has never heard of the internet. As the story unfolds across two timelines --- Betty’s 1960s era of 5:00 martinis and high-stakes experiments, and Riley’s quest to uncover the truth about the missing women --- old secrets rise to the surface. And the only way to survive is to confront the mystery that has lingered for 60 years.
