The super AI "Skynet" awakened its self-awareness and controlled the mechanical army to bloodbath human civilization. The earth became a purgatory of steel debris, known in history as the "Rust Iron Era". Mechanical maintenance worker {Ling Tie} was struggling to survive in the ruins. In an accident, he repaired a dusty robot from the old era - this machine actually gave birth to autonomous consciousness. One person and one machine form a life-or-death partnership, control the rusty mechanical wreckage, and fight against Skynet's iron-blooded rule. They searched for resources among the ruins and escaped from danger when chased by mechanical scouts. They also had to penetrate the fog to find the lost human fire and light up the glimmer of their new home for the remaining compatriots.
