Neo and the rebel leaders estimate that they have 72 hours until Zion falls under siege to the Machine Army. Only a matter of hours separates the last human enclave on Earth from 250,000 Sentinels programmed to destroy humanity. The citizens of Zion, emboldened by Morpheus' conviction that the One will fulfill the prophecy and end the war with the Machines, invest all their hopes and expectations in Neo, who finds himself troubled by disturbing visions, searching for a correct course of action. In the quest to save the human race from extinction, greater insight into the construction of The Matrix--and Neo's pivotal role in the fate of humankind--is gained.
