梅多斯小姐（凯蒂·霍姆斯饰）是个温柔而规规矩矩的普通小学教师，其完美的仪态和漂亮的印花连衣裙下却隐藏着一个不为人知的秘密——在没有教学任务或打理她的花园之外，她竟作为一个持枪维持治安的私刑独行侠。可是，在与小镇警长（詹姆斯·巴奇·戴尔饰）步入浪漫之后，她开始纠结......Prim schoolteacher Miss Meadows (Katie Holmes) is not entirely what she appears. Well-mannered, sweet, and caring, yes, but underneath the candy-sweet exterior hides the soul of a vigilante, taking it upon herself to right the wrongs in this cruel world by whatever means necessary. Things get complicated, however, when Miss Meadows gets romantically entangled with the town sheriff (James Badge Dale) and her steadfast moral compass is thrown off, begging the question: "Who is the real Miss Meadows and what is she hiding?"
