What is the Matrix, are you kinding? Anyways. Neo wakes up to Morpheus speaking to him on the computer one moment later he is being chased by agents, drones, and etc...just rent the frikn movie, or better yet...buy it!
Need more info? Fine. After Neo wakes up he follows "The White Rabbit" and after one rave and a sit down with Agent Smith he soon finds out his whole life is not only a lie, but computer generated lie, his and everyone elses. Its up to him and Morpheus' crew to bring out The One in Neo and go one step closser to shutting down The Matrix.
