Sam Price works for a company that assesses the merits and results of research projects as the “disinterested third party.” His company’s conclusions are often the deciding factor in whether or not the money keeps flowing to the researcher. Sam and his team, Sue and Nicole, are tasked with assessing the methods, tools, and results of a project that started as a way to find relief from phantom limb pain in amputees, but morphed into a study of how blocking brain waves in one hemisphere of the brain led to the other hemisphere compensating, thereby increasing a person’s ability to learn. It’s a routine part of Sam’s job, but Dr. Worthington, the scientist responsible for the brain wave study, is resistant to providing them with the information they need to assess his study and they have no way of contacting the study volunteer, a person known only as A.T.
When Worthington becomes violent and throws them out of his office, they become worried about his mental state and their own safety. They begin to wonder if he’s used his device on himself, and they begin to wonder what using such a device could do to the human brain. Here's a clue--what it does isn't a good thing!
