玛拉(裴淳华 Rosamund Pike 饰)经营着一家监护人公司,她专门寻找身体情况欠佳同时又无依无靠的老年人下手,通过并不是那么合法的手段令自己成为他们的法定监护人,将他们送进疗养院,之后便可接手和变卖他们的财产和房产,再将所得据为己有。 某日,玛拉将下一个“吞噬”的目标放在了一位名叫珍妮弗(黛安娜·维斯特 Dianne Wiest 饰)的老太太身上,经调查,珍妮弗没有任何的亲人,同时又拥有着价值不菲的遗产,简直就是他们的最佳“肥羊”。在一番操作之后,珍妮弗被没收手机关进了疗养院,但此时的玛拉和她的恋人兼合伙人弗兰(艾莎·冈萨雷斯 Eiza González 饰)并不知道的是,她们惹上了一个不该惹,也不能惹的人。Poised with sharklike self-assurance, Marla Grayson is a professional, court-appointed guardian for dozens of elderly wards whose assets she seizes and cunningly bilks through dubious but legal means. It's a well-oiled racket that Marla and her business-partner and lover, Fran, use with brutal efficiency on their latest "cherry," Jennifer Peterson - a wealthy retiree with no living heirs or family. But when their mark turns out to have an equally shady secret of her own and connections to a volatile gangster, Marla is forced to level up in a game only predators can play - one that's neither fair, nor square.
