What Next, Corporal Hargrove?

U.S. artillery corporal Marion Hargrove (Robert Walker (actor, born 1918)) finds himself at large in wartime France with wheeler-dealer pal Pvt. Thomas Mulvehill (Keenan Wynn). Inadvertently detached from their outfit, Hargrove and Mulvehill wander into a French village, where they're lauded as conquering heroes by the populace.
