The only way I could make any sense of this mess of a film was to assume that "Katie," Elle's mysterious "pen pal," was actually the creepy looking night clerk of the motel, who somehow knew that "Katie" was not present in the room adjacent to Elle. What actually happens to Ellie after she opens the door to her room at the end is not shown, but we must assume she was done in by "Katie," who then goes on to contact other naive girls via e-mail. Presumably, they will all wind up at the same motel late at night to be told the same thing by the night manager. None of the characters in the film were likable save for the Gay brother and his lover.
