After finding a mysterious old scientific text in her College’s library, young Danni Spivey is pulled headfirst into what at first seems to be a long forgotten experiment aimed at intradimensional travel. Diving deeper into the mystery, however, she becomes a vector for a phenomenon that begins replacing her loved ones. In their place are identical facsimiles, some of which are benign, while some seem to mean her harm. Her once loving boyfriend Ogden has been replaced by a hateful and manipulative man who shares his face, voice, and smell. At the same time, Danni wrestles with the idea that she might actually be losing her grip on reality. Perhaps the only thing changing in her world, is her perception of it. A tightly contained thriller that asks how far we might be willing to stretch our own deniability when finally coming face to face with the world as it truly is. Time is running out for Danni to decide what to do, and either choice will change her life forever.
