Mindwalk (The Turning Point) (1990)

On the French island of Mont Saint-Michel, Sonia meets Jack and Tom. Sonia is a Norwegian physicist who abandoned a lucrative career after discovering that elements of her work were being applied to weapons development. Jack is an American politician attempting to make sense of his recent defeat as a presidential candidate. Tom is a poet, disillusioned former political speechwriter, and Jack's close friend. As they wander the picturesque medieval abbey, the trio engage in a wide-ranging conversation on political and social problems, exchanging their varied perspectives rooted in their different intellectual backgrounds.
