San Diego private investigator Rick Cahill' s past comes back to haunt him when he' s at his most vulnerable. His wife, Leah, has fled with their daughter, Krista, to her parents' home in Santa Barbara. She fears Rick' s violent outbursts brought on by his potentially fatal brain disorder, CTE- and she doesn' t trust that he' ll ever be able to tame his manic desire to bring his own brand of justice to an unjust world.

Rick desperately wants to reunite his family and help provide for Krista' s future- one he fears he won' t be alive to see. A jumpstart toward that future appears in the form of Peter Stone, Rick' s longtime enemy. Stone offers Rick $50,000 to find a woman he claims can save his life with a bone marrow transplant. Rick can' t pass up the chance to buttress Krista' s future.
