Eighteen years after her stepmother Marguerite forced her out of her own bedroom into a cramped storage room, Claire finally owns a beach house entirely her own, only to face the same entitled demand when Marguerite announces she, her husband Gerald, and daughter Sabrina are moving in the next morning. Rather than arguing, Claire calmly prepares a cramped downstairs room identical to the one she was once exiled to, complete with four sealed envelopes waiting on the pillow.

As Marguerite opens her envelope and reads the first line, her confident smile vanishes completely, revealing that Claire hasn’t simply recreated old humiliation, she’s spent nearly two decades quietly gathering evidence, and whatever those envelopes contain is about to unravel far more than one awkward moving day.
