It's in the Bag on AllMovie

The popular British music hall and radio team of Gert and Daisy (Elsie and Doris Waters) heads the cast of It's in the Bag. The whole thing starts when the cackling cockney duo sells an old dress. Turns out that there's 20,000 pounds sewn in the lining of the frock, a fact that precipitates a merry chase. Also in pursuit of the money is Reginald Purdell, whose honesty is a matter of grave doubt. It's in the Bag comes to a literally explosive climax in a deserted theater.
