Killer Joe (2012)

When 22-year-old Chris (Emile Hirsch) finds himself in debt to a drug lord, he stumbles on the scheme of hiring a hit man to dispatch his mother, whose $50,000 life insurance policy is supposed to go to his sister Dottie (Juno Temple). Chris hires Joe Cooper (Matthew McConaughey), a creepy, crazy Dallas cop who moonlights as a contract killer. When Chris can’t pay Joe up front, Joe sets his sight on Dottie as collateral for the job.
