Steven and Laura Harding, along with their kids David and Mary, have moved to the quiet community of Stepford. Steven joins the men's club, which is still assimilating their wives into robots. This time, they have begun to turn their out of control teens into robots as well. Once they are assimilated, they are obedient, homework loving, big band dancing droids. Laura, David, and Mary stumble onto this mystery, and they must avoid Steven's plans to turn them into robots.
