At the end of the 19th century, with malaria having taken more veterans of the Spanish-American War than combat, Major Walter Reed (Lewis Stone) leads a U.S. Army Medical Corps contingent to Cuba with the mission of finding, and then stemming, the source of "Yellow Jack." Turning to the once-discredited theory that the disease is transmittable by mosquito bite, the doctors must find a handful of volunteer soldiers brave enough to put it to the test. Engrossing take on the acclaimed stage play also stars Robert Montgomery, Virginia Bruce, Charles Coburn, Buddy Ebsen, Andy Devine, Henry Hull. 83 min. Standard; Soundtrack: English Dolby Digital mono.
