Wanting to get married to bumbling steamship company file clerk Humphrey Briggs (Eddie Albert) and needing the money to buy a house, the scatterbrained Sally Elliot (Lucille Ball) takes a job selling cosmetics door-to-door. But when Humphrey's employer and his wife are both murdered by smugglers using their business as a front, the blame for the crime falls squarely on Sally. And after she and Humphrey are forced to flee, they must avoid the police as they try and track down the real killers on their own.
