Her estranged, panic-attack-prone sister April soon learns that Sandra has been secretly seeing April’s perpetually adrift son, Theo. Old wounds tear open as it’s revealed that, as teenagers, Sandra slept with Theo’s father while April was pregnant—just as Sandra now faces a diagnosis of early-onset Alzheimer’s. As secrets unravel, including the truth that Sandra is Theo’s biological mother, Sandra declares her wish for a legally assisted death in Switzerland. When their vitriolic mother, Diane, arrives, generations of lies erupt, leaving the family to confront betrayal, mortality, and the fragile possibility of forgiveness.
