Dan, an 18-year-old high school senior, lives with his mother’s best friend Paige, 32, for convenience. After accidentally witnessing an intimate moment between Paige and her husband Arnold, he becomes obsessed with her. Ambiguous encounters—dark bathroom run-ins and yoga contact—deepen his fixation. When Paige struggles with postpartum engorgement, Dan offers a “family lactation technique,” gaining her trust while pushing boundaries. As she wavers between resistance and acquiescence, Arnold returns drunk and interrupts. Later, Dan is kept after school, where he discovers teacher Delyse’s affair with the principal. Using this secret as leverage, he redirects his frustrated desires toward Delyse. What follows becomes a long, scorching summer spiraling out of control.
