What Is ‘There’s Someone Inside Your House’?

There’s Someone Inside Your House is based on Stephanie Perkins’s first thriller book.

The film and book follow Makani Young as she adjusts to her new life in a small Nebraska town. Then her classmates start to die in gruesome murders as graduation draws nearer.

The killer is set to expose all secrets in town and wears a mask of their victims’ faces as they chase them down. Makani and her friends set out to unveil the killer before they are the next targets.

The film is described as a modern-day Friday the 13th while still reminiscent of 80s and 90s flicks like The Breakfast Club.
