Looking Up (1977)

Rose is a part of a large Jewish family living in New York City who dreams of owning a fast-food burger restaurant. But trouble erupts when her sister Libby announces that her husband is facing prison time for fraud, and that her daughter's wedding plans will likely be canceled as a result. Then Rose discovers that her husband, Manny, is actually the father of Libby's child, prompting her to wonder if there is any point to her striving at all.
