A day in the barracks turns chaotic as a group of straight, muscular soldiers are taught a lesson in tolerance by their black, hung drill sergeant. The sergeant, unapologetic about his sexual preferences, leads the men through a series of intense, explicit drills, turning the recruits into a writhing mass of sweat and desire. Outdoors, in the sun, the soldiers are pushed to their limits, their straight boundaries tested as they're initiated into a world of gay pleasure.
