In The Edge Of, Sam went on a business trip to a convention without his wife. He was shocked to discover that she was sleeping in the middle of the afternoon when he arrived. Sam thought for sure that his wife would be so happy to see him after he was away for so long. His wife seems cold, and she doesn't have any interest in him at all. This is so strange because they were newlyweds who couldn't keep their hands off of each other. Sam then realizes a selfie his wife took and sent him while he was away, he didn't notice it at the time, but now he sees there are foreign fingers in the selfie. Could his wife be cheating on him behind his back?
