The story is set in California, United States, in 1984, the year of Ronald Reagan's reelection. After a scene in which former hippie Zoyd Wheeler dives through a window, something he is required to do yearly to keep receiving mental disability checks, the action of the novel opens with the resurfacing of federal agent Brock Vond, who (through a platoon of agents) forces Zoyd and his 14-year-old daughter Prairie out of their house. They hide from Brock, and from Hector Zuñiga (a drug-enforcement "federale" from Zoyd's past, who Zoyd suspects is in cahoots with Brock) with old friends of Zoyd's, who recount to the mystified Prairie the story of Brock's motivation for what he has done.
