Hiro Protagonist is a genius hacker, master swordsman, and unemployed pizza delivery driver lost in a post-war, hyper-capitalist future America, where the central government has withdrawn, leaving behind a chaotic landscape of fenced communities and endless highways with franchises and private armies.
When a virus (or is it a drug or religion?) called Snow Crash that infects both people and computers spreads rapidly, Hiro teams up with a young skateboard courier to save the real world and cyberspace.
