The Unknown Visitor Part 1: The Knock at Night

Logline
Two siblings. Ten days alone. One knock that changes everything. Some visitors don't leave.

Blurb
When their parents leave for a ten-day business trip, twenty-five-year-old Rose is left in charge of the family's isolated suburban home-and her fiercely independent fifteen-year-old brother, Liam. It was supposed to be a quiet, routine week of looking after the house and surviving each other's company.

But the quiet doesn't last.

It starts with a single, heavy knock at the front door in the dead of night. No delivery. No neighbor. Just a towering silhouette standing in the shadows of the porch, and a chilling realization: they are being watched.

As the days bleed into terrifying nights, the entity outside grows bolder, playing a psychological game of cat-and-mouse. Cut off from the outside world and realizing that calling for help might be too late, Rose and Liam must put aside their differences. From decoding cryptic polaroids left on their property to barricading the halls, the siblings are forced into a desperate fight for survival.

Whatever is outside wants to come in. And it's up to Rose and Liam to uncover the truth and put an end to the terror before the ten days are up-or they won't live to see their parents return.
