Rooted deeply in historic fact, Open Wound artfully fictionalizes the complex, lifelong relationship between Beaumont and his illiterate French Canadian patient. The young trapper's injury never completely heals, leaving a hole into his stomach that the curious doctor uses as a window to understand the mysteries of digestion. Eager to rise up from his humble origins and self-conscious that his medical training occurred as an apprentice to a rural physician rather than at an elite university, Beaumont seizes the opportunity to experiment upon his patient's stomach in order to write a book that he hopes will establish his legitimacy and secure his prosperity. As Jason Karlawish portrays him, Beaumont, always growing hungrier for more wealth and more prestige, personifies the best and worst aspects of American ambition and power.
