Sissy has an...interesting family. Always the careful one, always the cautious one, she has handled the cleanup while her serial killer sisters have carved a path of carnage across the U.S. Now, as they arrive in the Arizona heat, Sissy must step up and embrace the family pastime of making a man fall in love and then murdering him. Her first target? A young widower named Edison - and their mutual attraction is instant. While their relationship progresses, and most couples would be thinking about picking out china patterns and moving in together, Sissy´s family is reminding her to think about picking out burial sites and moving on. But then something happens that Sissy never anticipated: She begins to feel protective of Edison, and then, before she can help it, she´s fallen in love. But the clock is ticking, and her sisters are growing restless. It becomes clear that the gravesite she chooses will hide a body no matter what happens; but if she betrays her family, will it be hers?
