Rachel Jenkins is a successful architect who has been given the opportunity to design a new office complex. On returning home one day she finds her sister being attacked and in her efforts to stop the man, her building model is destroyed. To make matters worse, it turns out that her sister, an aspiring actress, was simply completing a class exercise with a friend and wasn't being attacked at all. As Rachel tries to re-do her project, her sister is continually completing varying acting exercises - elation, sorrow etc - so when a masked man forces his way into the apartment, she knows exactly what is going on. Or does she?
