After swallowing the red pill, Neo's reality disintegrates and he awakens, naked and weak, in a liquid-filled pod, one of countless people connected by cables to an elaborate electrical system.
He is rescued and brought aboard Morpheus' hovercraft, the Nebuchadnezzar.
She kisses Neo, and he revives, this time with the power to perceive and control the Matrix.
The Matrix is a 1999 science fiction action film written and directed by The Wachowskis, starring Keanu Reeves, Laurence Fishburne, Carrie-Anne Moss, Hugo Weaving, and Joe Pantoliano.
It depicts a dystopian future in which reality as perceived by most humans is actually a simulated reality called "the Matrix", created by sentient machines to subdue the human population, while their bodies' heat and electrical activity are used as an energy source.
Morpheus explains that, in the early 21st century, intelligent machines waged a war against the humans that created them.
When humans blocked the machines' access to solar energy, the machines retaliated by harvesting the humans' bioelectricity for power.
