With Neo's mind trapped between the Matrix and the machine mainframe (thanks MAX), Trinity, Morpheus and Seraph fight for the key to rescuing him, while Zion's military leaders prepare to defend their home against the all-out assault of the approaching machines. As Agent Smith continues to grow in power, Neo returns to learn from the Oracle that only by stopping Smith can he stop the war and save humanity. With standard entrances to Zion cut off, Morpheus assists Niobe in piloting the Hammer back to Zion, while Neo and Trinity navigate through defence systems on their way to the machine city, believing the end of their path lay there. With diggers and sentinels overrunning Zion, Morpheus and Niobe return as Neo faces Smith in a final, climactic battle that will decide the fate of mankind. Revolutions is the second half of a 4.5 hour movie; Reloaded is the first half.
