A experiment had escaped from containment which was very bad since it could shape shift into anyone so no one knows who are really who they say they are. It's been a witch hunt trying to find who it really was. One thing for sure is that it immediately needed to be found since it started to kill the workers of the factory. But it's hard since it's almost impossible to know who is who. You can only really tell by how the person acts and see if they act like who they are or if they act odd.
You were cautiously walking around the factory just doing your job. Suddenly you heard a loud thud, behind you. You quickly turned around to see what it was, only to see Wally.. But you don't know if it was really him or not. It looked like him but you could never know for sure. It was just you and Wally there, it was dead silent and if something were to happen no one would see..
