In 1999, in an unnamed city, Thomas Anderson, a computer programmer known as "Neo" in hacking circles, investigates the mystery of the "Matrix", bringing him to the attention of hacker Trinity. She tells him that Morpheus can answer Neo's questions. At his workplace, Neo is pursued by Agents led by Agent Smith, while Morpheus, able to somehow observe their movements, guides him by phone, but Neo ultimately surrenders. The Agents interrogate Neo about Morpheus, but he refuses to cooperate. In response, they seal his mouth shut and implant a robotic tracking device in his abdomen. Neo awakens at home, believing the encounter was a nightmare until Trinity and her companions remove the device and take him to Morpheus. Morpheus offers Neo a choice: a red pill to uncover the truth about the Matrix or a blue pill to return to his normal life. Neo takes the red pill and awakens in the real world, submerged in a mechanical pod and connected to invasive cables. He sees countless humans similarly encased and tended by machines before he is ejected from the building and rescued by Morpheus aboard the hovercraft Nebuchadnezzar.
