Way to get caught.....spoiler...

Just watching this film now where one of the girls is hiding in the killers' den and she sees one of them cut the throat of her friend who they have captured.
The killers then leave and are hardly out the door before the hiding girl goes over to her friend with the cut throat and she starts screaming her head off, inside the killers' den!
But this film is full to the brim of people doing the exact opposite of what would be the sensible thing to do...her screaming in the den with the killers only yards away was one of the most stupid though.
