In the not-too-distant future, robots are fighting for their equal rights. When a mysterious and deadly disease known as 'Rust' threatens all artificial life, salvation lies in the unlikeliest of heroes-an obsolete construction worker known as HALE-19 and AMBER-7T, a caregiver. Pursued by police and bounty hunters alike, HALE-19 must confront his sordid past and place his trust in his former unscrupulous allies to survive. But will they aid him in AMBER-7T's quest to save robot-kind? Or will they turn him in for the ultimate payday?
