Becky brings her kids to the beach house she inherited from her grandmother, expecting comfort but finding a wreck: booze-stained carpets, smashed furniture, and a stranger’s snoring in the bedroom. The “stranger” is her mother-in-law, Susan, who admits she used a spare key to rent the place to art students for a cash party. Becky is gutted—the house held her best childhood memories.

Becky orders Susan to clean and pay for damages; Susan scoffs that it’s “just a house.” Becky calls her husband, Steven, who arrives with gloves and trash bags, backs Becky completely, and helps restore order while the kids wait on the beach. By sunset the house is livable, and Becky sets a firm boundary: Susan will cover repairs—or stay away.

The next day Becky changes the locks; Susan later calls begging to stay after a burst pipe at her own home. Becky refuses, reminding her of the cash she made off the illegal rental. With windows open and sea air rolling in, the family keeps cleaning and repairs what they can, choosing peace over drama.

They reclaim the weekend: fish and chips, sandcastles, and plans for bunk beds and curtain colors. The house begins to feel like theirs again—not because it’s perfect, but because they protect it. Becky realizes home isn’t the furniture; it’s the people who show up for it. That night she finally sleeps, not to escape, but to rest.
