S3·E5 Stream of Consciousness

In a world where neural implants allow everyone instant access to information, Ryan Unger is a throwback, a moron. Because of a brain injury he suffered as a child, he's unable to tap into the Stream -- an electronic collection of all human knowledge -- so he struggles in vain to keep up by reading books, a primitive and forgotten art. But, when a virus in the Stream starts killing people by overloading their brains with data, only Ryan has the skills and independence to stop it. Can a primitive human, relying only on books and his own brain, save a world of machine-made geniuses from self-destruction or will the Stream wash over all of them?
