The stooges are greeting card salesmen who are mistakenly inducted into the army after escaping from the jealous husband of one of their customers. In bootcamp their sergeant turns out to be the same man, whom they constantly vex and bewilder. When the boys are sent to the front lines and the sergeant is captured they must rescue him, which they do after doping themselves with laughing gas. At the end they get shot off into the sunset on a cannon shell. Greeting card salesmen Larry, Moe and Curly hide from an irate man in what they think is a bread line and find themselves inducted into military service. Title is a parody of MGM film “Babes in Arms” (1939) starring Judy Garland and Mickey Rooney. (thetvdb.com)
