There were several things which should have alerted him and Claire that this visit was not a good idea.
Thirteen, an address which might be a clue that something bad could happen. Another should have been interviewing the survivor of a serial killer rampage.
However, this shoot for a future movie was going to include an interview with Laura, who was the miraculous only survivor.
When they arrived at 13 Callaway Place, the movie equipment was set up inside, but the crew had evidently left. He assumed they had left to get some breakfast in Chewela. The contract didn’t authorize them to leave the site until after the interview.
Barry went to move the car behind the house, but the battery had crapped out. When he went back inside, he couldn’t find Claire. Laura was in the kitchen with her when he went outside. He noticed the movie scene plate on the floor, so the camera crew was definitely here and had shot one take without him.
He decided to fire up the camera and review what they had shot. They were indeed doing a preliminary shoot of Laura’s interview, but suddenly a shadow appeared and the camera stopped recording.
He heard something behind him, and turned, expecting to see Claire.
When he regained consciousness, he had indeed found Claire and the camera crew, and now realized how Laura had survived the rampage. He and Claire were now part of Laura’s own serial-killer production.
