Magic TV: It's Not a Set

Sarah walked as briskly down the hall as she could, trying to find a way out. This was obviously some sort of movie set. All she had to do was find the end of the set and get out of there. But as she kept walking, she saw that there was no way out. "Is there *any* end to this hallway?" "Seven?" someone asked. Sarah heard the person, but she kept on walking, ignoring them. "Seven?" the voice said a little louder, with more urgency. Whoever the person was, the voice was being directed towards Sarah, although she had no idea why. "Seven, stop!" the voice demanded. Yeah, it was definitely being directed towards Sarah. She spun around and glared at the person yelling at her.
