The boys' Army buddy Eddie Smith is killed in the trenches in France, leaving his baby girl an orphan. Back home after Armistice, they try to find Eddie's father and turn the child over to him. Unfortunately, they keep coming up with the wrong Smiths, and in the process disrupt a wedding by proclaiming the baby to be the groom's child. To evade the Welfare Association, they try to skip town, raising money for their escape by hocking their lunch wagon. But they accidentally knock the bank president unconscious and wind up being hunted down for bank robbery.—Paul Penna
