A grim fantasy has a palpably constructed setting for the discussion of freedom-people trapped in a Manhattan subway by explosions they suspect have demolished the city above. Art, a would be suicide, decides he wants a second chance, and is instrumental in saving a group he leads down through the subway. They meet another group led by a tyrant. Art revolts, is betrayed, but eventually gathers enough support for a successful revolution. The suspense setting lends impetus to a discussion of the evils of prejudice, inequality and power. Provocative.
