The plot centers around Chevette Washington, a young bicycle messenger who lives in the ad hoc, off-the-grid community that has grown on the San Francisco-Oakland Bay Bridge in the aftermath of a devastating earthquake. Chevette, on a whim, steals a pair of dark-rimmed glasses from a man at a party because she is offended by his demeanor. Soon after, she realizes that the glasses have unlikely importance, as security company henchmen begin tracking and following her. Among the pursuers are Svobodov and Orlovsky, two Russian immigrants who reside in San Francisco and are employed as cops, as well as Loveless, a ruthless corporate hitman with gold incisors. The glasses contain plans by a powerful corporation to rebuild San Francisco entirely using nanotechnology, and for that reason, they are highly coveted and present a danger to the person who possesses them.
