Neighborhood children begin to play a game called 'invasion'. It is
taught to them by a being that lives in a rose bush. Parents begin to
notice that kids all over the country are playing a similar game,
collecting scrap parts of metal. The kids tell the parents that the game
is about martians invading the planet and that they need the kids to
help. Unfortunately for the adults, they only believe that it is a
harmless childrens game.
