Set in contemporary Northern California, The Harder They Come explores the volatile connections between three damaged people--an aging ex-Marine and Vietnam veteran, his psychologically unstable son, and the son's paranoid, much older lover--as they careen towards an explosive confrontation. On a vacation cruise to Central America with his wife, seventy-year-old Sten Stensen unflinchingly kills a gun-wielding robber menacing a busload of senior tourists. The reluctant hero is relieved to return home to Fort Bragg, California, after the ordeal--only to find that his delusional son, Adam, has spiraled out of control. Adam has become involved with Sara Hovarty Jennings, a hardened member of the Sovereign Citizens' Movement, right-wing anarchists who refuse to acknowledge the laws and regulations of the state, considering them to be false and non-applicable. Adam's senior by some fifteen years, Sara becomes his protector and inamorata. As Adam's mental state fractures, he becomes increasingly schizophrenic--a breakdown that leads him to shoot two people in separate instances. On the run, he takes to the woods, spurring the biggest manhunt in California history.
