Coming home with a bag of sugar for the same borrowing that had quietly given her neighbor Camille access to her house for months, Delphine discovers her husband Marcus and Camille together in the backyard pool they’d spent two summers building. Rather than confronting them with anger, she calmly folds their clothes, sets down the sugar, and presses the security alarm she’d installed years earlier, the same system Marcus had once mocked as unnecessary.

As the alarm sounds and neighbors step onto their porches to watch, a second vehicle pulls up outside the fence, and whatever Camille whispers upon recognizing who’s climbing out of it suggests the fallout from this discovery is about to reach far beyond Delphine’s own marriage.
