In late-twenty-first-century England, the Bell family, looking to replace their malfunctioning robot, buys Eager, who is programmed to learn through trial and error like humans and who, with the Bell children, comes to see that something is not right with the BDC4s, a sleek, alarmingly clever line of robots the Bells could not afford.
