Korean War--era veterans and ex-classmates "Gunner" Casselman and "Sonny" Burns reunite upon their return home. Gunner, who spent the war years abroad, is trying to convince his mother that his gal Marty is good enough for him, while Sonny, who was stationed stateside, is torn between loyal Buddy and tempting Gale Ann. As they commiserate, the men realize that they're outgrowing the lives they lived before the war.
