Over the course of a fall weekend, Sybil reunites with Nora, a woman with whom she shares a complicated past and an intimacy neither has fully escaped, at the home they once shared in upstate New York. Old resentments, unresolved grief, and buried truths begin to surface. As Sybil's fiancé, Ben, further disrupts the fragile balance, Artemis — an enigmatic presence who seems to know more than she should — pushes them all to confront the stories they've told themselves and each other.
