In the high-stakes world of Texas oil, charming con man Henry Tyroon, played by James Garner, makes a living by selling dry wells to gullible investors. His latest scheme, however, takes an unexpected turn when he crosses paths with the shrewd and sophisticated Eastern banker, Molly Thatcher, portrayed by Lee Remick. As Molly arrives to assess the financial viability of Henry's operations, a battle of wits and wills ensues, with the swindler determined to outmaneuver the analyst sent to expose him. Directed by Arthur Hiller, this action-thriller blends sharp wit with a sun-baked atmosphere of risk and deception, as Henry's elaborate cons are threatened by Molly's penetrating intelligence. Supported by a colorful cast including Phil Harris and Chill Wills, the film charts a course through a landscape where fortunes are made and lost on a handshake, and the greatest gamble of all might just be falling for your mark.
