Commander John Lane returns from a ten-year mission in space
to find that the teenagers of Spaceport City have organized
themselves into "outfits", well disciplined, non-violent little gangs with their own customs and argot, and that the parent's
role in teen upbringing has become minimal. His 16-year-old
daughter Susan belongs to the Red Cat Outfit, whose newest member
Bud is actually a spy for the alien fleet that has secretly followed John Lane as he returned to Earth.
