“Never trust your neighbors.”
The housemaid is watching everything!

Millie is married to Enzo and is now the mother of two children.
The Millie family, who lived in a small house in New York, moved to a single-family home on Long Island.
Although it was a bit of a stretch to take out a loan given her tight finances, having a home meant a lot to Millie, who had been out of prison and sleeping in her car.
But Millie's hopes for happy days didn't last long.


The woman next door kept flirting with Enzo in front of Millie, and the woman in front was always spying on our house, which was annoying.
Moreover, I kept having trouble sleeping because of strange noises coming from the house every morning.
Millie, whose stress was at its peak, decided to go to the woman next door and say something sharp to her.
Get away from my husband.
But when I opened the door and went inside, there was a corpse lying there with its throat cut.
And then a siren was heard from afar.


Once again embroiled in a murder case, will Millie be able to protect her family and the happy life she's dreamed of? A heart-pounding psychological thriller.

The film, starring Amanda Seyfried and Sydney Sweeney, is set for release in late 2025!
