Swing It Soldier

Jerry Traynor, an Army conscriptee (peace-time draftee), is released from the service, and returns to his job as a radio executive, after promising his army-buddy, Bill Walters, to look out after his wife, Evelyn, who, although expecting a baby, is also pursuing a singing career in radio. He mistakes Evelyn's twin sister, Patricia, for the wife whose welfare he is to guard.
