Shrewd U.S. Attorney Chuck Rhoades is embroiled in a high-stakes game of predator vs. prey with the ambitious hedge-fund king, Bobby Axelrod. To date, Rhoades has never lost an insider trading case -- he's 81-0 -- but when criminal evidence turns up against Axelrod, he proceeds cautiously in building the case against Axelrod, who employs Rhoades' wife, psychiatrist Wendy, as a performance coach for his company. Wendy, who has been in her position longer than Chuck has been in his, refuses to give up her career for her husband's legal crusade against Axelrod. Both men use their intelligence, power and influence to outmaneuver the other in this battle over billions.
