In a quiet cul-de-sac with perfect lawns and matching mailboxes, Marjorie Ellington is the kind of neighbor everyone thinks they want.

She bakes. She waves. She walks the block three times a day “for exercise.” She also happens to be the HOA president—and the only person, in her opinion, who still cares about community standards.

Overflowing trash cans. Screaming children. Oil-stained driveways. Dogs that use her lawn as a toilet. Marjorie sees it all, writes it all down, and makes sure every act of disrespect is answered with a correction. Some are petty. Some are vicious. And one of them is final.

When Markus Alvarez, the cul-de-sac’s loudest, messiest, most entitled resident, pushes her too far with his illegal garage business and revving engine, Marjorie decides it’s time for a more… permanent solution. After all, a good neighborhood doesn’t protect itself.
