It’s several months after the events of the first film, and the last remaining human city, the underground bunker called Zion, is building its forces to take back the planet from the artificial intelligence that now dominates it. This same artificial intelligence has begun to dig to destroy Zion, and the resistance seems overwhelmed by the potential onslaught. The plan is now hatched to send agents Neo (Keanu Reeves), Trinity (Carrie-Anne Moss), and Morpheus (Laurence Fishburne) back into the Matrix so that they may destroy the mainframe that controls it, but it’s not going to be easy, with the usual agents, a couple of ghosts, and hundreds of Agent Smiths (Hugo Weaving), who now seems to have the ability to replicate himself, on their tails.
