At the end of the last film, Neo (Keanu Reeves) finally realized his ability and mission. After being shot and resurrected, he became an omnipotent "savior". He and his girlfriend Trinity (Carrie-Anne Moss) and Captain Morpheus (Laurence Fishburne) returned to the human base Zion and were warmly welcomed by the people. At this time, the "Matrix" decided to take the initiative and sent 25,000 electronic squids to attack the Zion base; Morpheus, Neo and Trinity entered the "Matrix" again to find the "Key Maker" and prepare to destroy it from the inside; and Special Agent Smith, who should have been eliminated by Neo, seemed to have some problems. He was out of the control of the "Matrix" and had a terrible replication ability, which hindered Neo's actions.
