It is summer, and obsessed Ralf Gordon (Anthony James) stalks a high-school teacher, 28-year-old Diane Marshall (Angel Tompkins). He watches her from an old warehouse while she is relaxing in her swimsuit on one of the boats. One of Diane's students, 18-year-old Sean Roberts (Jay North) and Ralf's younger brother Lou (Rudy Herrera, Jr.), also watch her strip naked and exercise. An angry Ralf yells at them, brandishing a bayonet. Shocked at this, Lou falls over the railing to his death, for which Ralf falsely blames Sean.
