The Family That Preys

This 2008 movie written, directed and produced by Tyler Perry is about the inner workings of two families--one upper crust and the other working class--that become inextricably linked by scandal. Wealthy socialite Charlotte Cartwright and her dear friend Alice, a working-class woman of high ideals, have enjoyed a lasting friendship throughout many years. Suddenly, their lives become mired in turmoil as their adult children's extramarital affairs, unethical business practices and a dark paternity secret threaten to derail family fortunes and unravel the lives of all involved. There are a lot of spoilers here due to the nature of the movie.
