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.
Neo and the rebel leaders estimate that they have 72 hours until 250,000 probes discover Zion and destroy it and its inhabitants. During this, Neo must decide how he can save Trinity from a dark fate in his dreams.
