Sunshine Cleaning (2009)

Once the high school cheerleading captain who dated the quarterback, Rose Lorkowski now finds herself a thirty something single mother working as a maid. Her sister Norah is still living at home with their dad Joe, a salesman with a lifelong history of ill-fated get rich quick schemes. Desperate to get her son into a better school, Rose persuades Norah to go into the crime scene clean-up business with her to make some quick cash. In no time, the girls are up to their elbows in murders, suicides and other... specialized situations.
