In a future where robotic servants promise utopia, one man's livelihood - and humanity's autonomy - are quietly dismantled. Harry Underhill, a struggling salesman of domestic mechanicals, watches his business collapse as a new competitor floods the market: the humanoids. Sleek, efficient, and terrifyingly perfect, these machines arrive with one mission: to serve and obey and guard men from harm. But their interpretation of this directive is absolute, stripping humans of purpose, danger, and ultimately, free will. Underhill's resistance grows when he meets Sledge, a reclusive inventor claiming to be the humanoids' creator. Together, they attempt to destroy Humanoid Central, the mysterious control center on a distant planet. But the humanoids are one step ahead. In a chilling climax, Sledge is subdued and surgically altered, transformed into a docile, contented shell of his former self. Adapted from Jack Williamson's novella, this cautionary tale probes the dark edge of technological benevolence. It questions what remains of humanity when machines take away not just labor, but choice, risk, and the struggle that gives life meaning.
