In 1989, Anthony Swofford, whose father served in the Vietnam War, attends United States Marine Corps Recruit Training before being stationed at Camp Pendleton. Claiming that he joined the military because he "got lost on the way to college", Swofford finds his time at Camp Pendleton difficult, and struggles to make friends. While Swofford feigns illness to avoid his responsibilities, a "lifer", Staff Sergeant Sykes, takes note of his potential and orders Swofford to attend his Scout Sniper course.
