The Intruder

In the middle of a storm, a girl appears on Casey's doorstep, obviously in need of help. She's young. She's alone. And, Casey soon learns, she's desperate.

The girl is clearly running from something, but she won't say what. When Casey tries to look learn more, she gets hostile. When Casey discovers disturbing diary entries and drawings in her meager backpack, she gets violent. This will be the longest night of Casey's life.
