Paige, however, just can't seem to let go. She is still consumed by grief, withdrawn, and unable to work. In order to supplement Paige's lost income, the family decides to rent out their spare bedroom.

A student at the local university, Brandon eerily resembles everything that Zach stood for in the family, and he brings Paige out of her shell. At first, Nathan and Addie are thrilled to see Paige acting more like her old self, but as Brandon insinuates himself further into the family, they start to see a darker, and more dangerous side of their tenant. Soon, Addie uncovers a secret about Brandon that is about to shake the Deckers to their core. Can a family in crisis hold themselves together in the face of an evil genius? 　　译文(2): 一年前 Paige 和 Nathan Decker 悲惨地失去了他们十几岁的儿子 Zach 死于吸毒过【资源囤-ZiYuanTun.Com】。内森和女儿艾迪正在慢慢恢复他们的生活。然而，佩吉似乎就是放不下。她仍然沉浸在悲伤中，孤僻，无法工作。为了弥补佩吉失去的收入，这个家庭决定出租他们的空余卧室。令人惊讶的是，生活开始期待佩奇一旦他们迷人的新房客，布兰登威尔逊，进入图片。布兰登是当地大学的一名学生，他与扎克在家庭中所代表的一切有着惊人的相似之处，他把佩吉从她的壳里带了出来。一开始，内森和艾迪很高兴看到佩吉表现得更像以前的自己，但随着布兰登进一步融入这个家庭，他们开始看到租客更黑暗，更危险的一面。不久，艾迪就揭开了布兰登的秘密这个秘密将震撼德克家族的核心。一个陷入危机的家庭能在邪恶的天才面前团结起来吗？
