8-year-old Jenny (Violet McGraw) is constantly caught in the middle of the feuding between her lawyer mother Maggie (Mamie Gummer) and artist father Jeff (Rupert Friend). She leads a lonely but imaginative life, surrounded by puppets called "Grisly Kin", which are based on the works of her father. When Maggie is tragically killed in a hit-and-run, Jeff and Jenny try to piece together a new life. But when Maggie's father (Brian Cox) sues for custody, and babysitter Samantha (Madeline Brewer) tries to be the new woman of the house, life in their Brooklyn townhome takes a dark turn. The puppets and frightening characters come to life and Jenny is the only person who can see them. When the motives of the ghoulish creatures become clear, the lives of everyone are put very much in jeopardy. 导演想告诉你：这是恐怖的家庭伦理悬疑剧。恐怖片吧！其实也不算太恐怖的。故事的梗不难猜，本来想是不是这两个漫画出版商会阴男主一把，结果还是小保姆的占有欲太强造成了一切。帮忙拉点分数，悬疑还是大要素。会不会黑白条才是boss。 故事讲述8岁的珍妮经常被她的律师妈妈麦琪和艺术家爸爸杰夫之间的不和所困扰。她过着虽然孤独但却很富有想象力的生活，身边还有一群以她父亲的作品为原型、被称为“恐怖亲戚”的木偶。麦琪在一起肇事逃逸事件中不幸身亡，杰夫和珍妮试图开始新的生活。但当麦琪的父亲起诉要求抚养权，保姆萨曼莎试图成为这个家的新女主人时，他们在布鲁克林的乡村小屋生活发生了一个黑暗的转折。可怕的木偶竟然都活过来了，珍妮是唯一能看到他们的人。当这些恐怖生物的动机变得清晰时，每个人的生命都处于非常危险的境地......
