Sunshine Cleaning (2008)

Though they once seemed to have a bright future, life seems to be passing by the Norkowski sisters. Rose (Amy Adams), once the most popular girl in high school, is a single mom and works as a maid. Norah (Emily Blunt) still lives at home with their father (Alan Arkin) and parties all the time. When Rose's married lover tells her about the lucrative field of crime-scene cleanup, she pours all her remaining resources into her new business, and recruits the squeamish Norah to help.
