It was Cobb Anderson who built the "boppers"—the first robots with real brains. Now, in 2020, Cobb is just another aged "pheezer" with a bad heart, drinking and grooving an the old tunes in Florida retirement hell. His "bops" have came a long way, though, rebelling against their subjugation to set up their own society an the moon. And now they're offering creator Cobb immortality but at a stiff price: his body his soul ... and his world.
