For Pete's Sake(1974)
Henrietta Robins works out of her home and her husband Pete drives a cab to try to support her. When Pete gets a tip from one of his fellow drivers that a deal will be made by the Americans and the Soviets over pork bellies, he decides to invest in the market, but needs to $3000 to invest. Henrietta then goes to extreme lengths to get the money by dealing with first a loan shark, then a madame, then the mob and finally cattle rustlers. All this in the name of love.
This is a vintage TV spot.
