In the quiet suburb where high‑school corridors echo with whispered plans for the biggest night of the year, a sense of anticipation crackles in the air. The looming prom, with its glossy dresses and flashing cameras, promises a brief escape from everyday pressures, yet a lingering unease hovers just beyond the decorated walls, hinting that not every memory can be neatly tucked away.

Donna returns to this familiar world carrying the weight of a traumatic night that still haunts her dreams. Surrounded by her steadfast friend Lisa and the lively Claire, she tries to balance the excitement of a new dress and a promise of normal teenage moments with the lingering shadows of her past.
