The film concentrates on a group of raw Marine volunteers. The first half details the volunteers' harrowing boot-camp training where under the profane, power-saw guidance of drill instructor Sgt. Hartman the recruits` personalaties dehumanize.
The second part takes place in the city of Hue in Vietnam, as seen through the eyes of the now thoroughly indoctrinated marines. One of them, Joker, covers the war as a correspondent for Stars and Stripes, focusing on the Tet offensive.
