Finally freed from the illusion of the Matrix, humans concentrate their resistance in Zion, the last real city beneath the surface, now threatened by an army of machines tunneling relentlessly toward it with barely seventy-two hours to spare. Neo, increasingly aware of his power as the One, must venture once more into the simulated world alongside Morpheus and Trinity to find the Keymaker, the key to reaching the Source. Along the way he uncovers unsettling truths about the origin of the prophecy and the true role of the Matrix. An ambitious sequel, loaded with choreography and philosophy.
