A man tumbles out of the door and falls, slides and slithers down two flights of stairs and is dead when he hits the bottom. Then follows nearly 100 minutes of flashback and flashbacks-within-flashbacks about a veteran returing from the war, tired and disillusioned, only to find that he girl he loves has lied to him about her relationship with another man, and that man is sadistic, boastful and tauntful.

　　Charlie and Ben pay a visit to a pub, then decide to visit a swanky restaurant. Now intoxicated, they come into conflict with a French dandy and his ladyfriend. The large head waiter violently ejects Ben, and later ejects Charlie also. The pair pay another visit to a pub, then make their way to their hotel. They become interested in a pretty young woman staying in the room across the hall, but when Charlie spies on her through the keyhole a bellboy makes him stop. Charlie is taken aback to realize that the young woman's husband is the head waiter from the restaurant. He promptly checks out and moves to another hotel. Meanwhile, the head waiter and his wife, dissatisfied with the service, also decide to move to another hotel-- and, unfortunately, choose the same one Charlie has chosen, and once more wind up in the room across the hall from him. When the young woman's dog runs into Charlie's room she follows in her pajamas. Her husband returns to find his wife with Charlie in an apparently compromising position.
