Armistice has been twenty years ago but doughboy Stan still patrols his trench in France — simply because no one told him the war was over.
His rescue coincides with the first wedding anniversary of his old pal Oliver Hardy. Heading to town to pick up a gift for his wife, Ollie discovers the picture of his old pal in a newspaper who is now living at the Veteran's Home. At first, Ollie takes pity on him, thinking that Stan is disabled because he look as if he has lost a leg (but he is only just sitting on it).
The two buddies share a warm reunion, whereupon Ollie invites Stan home to enjoy a nice home cocked meal, prepared by Mrs. Hardy.
As a result of Ollie's hospitality, Stan inadvertently wrecks Ollie's brand new car; the boys spend half the afternoon trudging up and down 13 flights of stairs; Ollie gets into a fight with belligerent Mr. Finn; Mrs. Hardy angrily walks out on her husband; the boys manage to blow up the kitchen while preparing their own meal; and Hardy's beautiful next-door neighbor ends up minus her dress in Ollie's steamer trunk, with both Mrs. Hardy and the neighbor's husband, big-game hunter Gilbert, returning unexpectedly upon our bethumped heroes.
