影片改编自苏珊·斯卡夫·梅瑞尔小说，背景设置在上世纪60年代，讲述了一对年轻夫妇(勒曼、杨饰)搬去与美国哥特惊悚小说家雪莉·杰克逊(莫斯饰)及其丈夫(斯图巴饰)同住，他们因此卷入一场心理惊悚事件，而这也为杰克逊的下一部小说提供了素材。

Women on the Run. Vera has lived a wonderful life with Jindrich, and she is fully determined to fulfill his last wish - running a marathon. The emancipated and spirited mother of three daughters doesn't think that doing so will be a problem. She and her daughters will split up the route into four parts, and they'll overcome the over 42-kilometer-long challenge as a family relay team. Of course, the fact that neither of them has ever ran even a meter poses no problem.
