In a small southern town, locals resent the nearby presence of an Army base, mostly because of the trouble stirred up by enlisted men. Officer Michael M. Nace (Brian Keith) is in charge of community relations and thinks a dance might do the trick, but it only serves to rile up locals and soldiers even more. Things come to a head when the town sheriff (Ernest Borgnine) arrests Nace's buddy, Sgt. Gambroni (Tony Curtis). Jeopardizing his career, Nate borrows a tank in order to spring him.
