In this second adventure, 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 mankind. But the citizens of Zion, emboldened by Morpheus conviction that the One will fulfill the Oracles Prophecy and end the war with the Machines, rest all manner of hope and expectation on Neo, who finds himself stalled by disturbing visions as he searches for a course of action.
