The Agents, led by Agent Smith, apprehend Anderson and threaten him into helping them capture the “terrorist” Morpheus. Undeterred, Anderson later meets Morpheus, who offers him the choice between two pills; the red one to show him the truth about the Matrix, and the blue one to return him to his former life. After Anderson swallows the red pill, his reality disintegrates. Neo awakens in a liquid-filled pod among countless others attached to an elaborate electrical system. He is retrieved and brought aboard Morpheus’ hovercraft, the Nebuchadnezzar.
As Neo recuperates from a lifetime of physical inactivity, Morpheus explains the truth. In the 21st century, there was a war between humans and intelligent machines. When humans blocked the machines’ access to solar energy, the machines responded by harvesting the humans’ bioelectric power, keeping them pacified in the Matrix, a shared simulated reality modeled after the world as it was at the end of the 20th century.
