[2] A young man named Jiron Amos is found in the desert by a group of bandits known as the Sand Rats (Rag, Blume, Dyke and Chill).

Jiron hopes to steal the Walker Machine Xabungle from the local trader Carrying Cargo to use it to take revenge against the Breaker who killed his parents, Timp Sharon.

Her father's top Breaker, Kid Horla hopes to marry Elchi and gain the license, but she rejects him and he flees.

Following orders from the Innocent, Timp recruits several other Breakers and traders to defeat the Iron Gear including Gavlet Gablae and Bigman but they all fail and are killed.

The Iron Gear battles Biel, now living in another Innocent dome, and Jiron steals the Walker Machine Gallier, which he pilots for the rest of the series.

Elchi is put under an intense level of brainwashing by the Innocent, who cause her to desire the Iron Gear's destruction and Jiron's death.

Katakam's methods are not respected however, and when everyone believes him to have been killed, he disappears from view, enabling Jiron to take on leadership of Solt.

Jiron and Solt hope to meet up with Innocent leader Arthur Rank, although his influence has been significantly reduced through the efforts of the villainous Kashim King.
