Please Give (2010)

Kate (Catherine Keener) and her husband Alex (Oliver Platt) are wealthy New Yorkers who prowl estate sales and make a tidy profit reselling items they bought cheaply. They buy the apartment next door and plan to remodel just as soon as its current occupant, a cranky old woman, dies. Kate is troubled by the way she and her husband earn a living, and tries to assuage her guilt by befriending her tenant and the woman's granddaughters, but her overtures lead to unexpected consequences.
