The Night They Robbed Big Bertha's (1975)

Big Bertha is the popular, full-figured owner of the community's most successful whorehouse and moonshine racketeering enterprise. Some guys decide to rob Big Bertha’s stash of money, but the local cops just happen to coincidentally be "visiting" the joint. With her money missing, Big Bertha announces the closure of her whorehouse, but nobody in town will let that happen!
