Neo (Keanu Reeves) believes that Morpheus (Laurence Fishburne), an elusive figure considered to be the most dangerous man alive, can answer his question -- What is the Matrix? Neo is contacted by Trinity (Carrie-Anne Moss), a beautiful stranger who leads him into an underworld where he meets Morpheus. They fight a brutal battle for their lives against a cadre of viciously intelligent secret agents. It is a truth that could cost Neo something more precious than his life.
In the third installment, the epic war between man and machine reaches a thundering crescendo: the Zion military, aided by courageous civilian volunteers like Zee and the Kid, desperately battles to hold back the Sentinel invasion as the Machine army bores into their stronghold. Facing total annihilation, the citizens of the last bastion of humanity fight not only for their own lives, but for the future of mankind itself.
Six months after the events depicted in The Matrix, Neo has proved to be a good omen for the free humans, as more and more humans are being freed from the matrix and brought to Zion, the one and only stronghold of the Resistance. Neo himself has discovered his superpowers including super speed, ability to see the codes of the things inside the matrix and a certain degree of pre-cognition. But a nasty piece of news hits the human resistance: 250,000 machine sentinels are digging to Zion and would reach them in 72 hours. As Zion prepares for the ultimate war, Neo, Morpheus and Trinity are advised by the Oracle to find the Keymaker who would help them reach the Source. Meanwhile Neo's recurrent dreams depicting Trinity's death have got him worried and as if it was not enough, Agent Smith has somehow escaped deletion, has become more powerful than before and has fixed Neo as his next target.
