In the second episode, Neo (Keanu Reeves) failed to destroy the "Matrix" from the inside. His body was in a coma on the real-world spacecraft, and his mind was trapped in the middle of the "Matrix" and the real world, where the "Train" controlled the spacecraft. Morpheus (Laurence Fishburne) and Trinity (Carrie-Anne Moss) learned about Neo's situation and, under the guidance of the guardian angel, found the controller of the "Train" Merovanchi. After some fierce fighting, Neo was rescued. At this time, the electronic squid troops launched a fierce attack on Zion, and all the mecha warriors organized by humans launched a tenacious resistance. The situation was at stake; Neo and Trinity drove a spacecraft to overcome numerous difficulties and arrived at the machine city. Neo finally met the ruler of the machine world, the "Machine Emperor", and the two sides negotiated and reached an agreement: Neo got rid of Smith, who was not controlled by the "Matrix", in exchange for the peace of Zion. In "The Matrix", Neo and Smith launched the final duel concerning the survival of mankind.
