A young couple Mira (Abbie Cobb) and Todd (Sean Faris) hire a live-in nurse (Lyndon Smith) to be the caregiver for their sick son, only to discover that she is an "angel of death" intent on replacing Mira through any means necessary.。英格丽·褒曼是支撑起这部电影的最大亮点,剧情在针对爱情中的背叛和夫妻间的诚实话题上刻画得颇有建树,特别是在动机得设计上足以称得上悬疑片。。
