TIPPIE was created to be a weapon. By all appearances, she's an ordinary girl of 18, and she uses that to her advantage in her work for The Facility. What no one sees is that there's another girl buried deep inside. She can't speak or control the movements of the body she inhabits. As TIPPIE's silent passenger, she can only observe. She uses the details she learns from TIPPIE's work to reconstruct the stories of other people's lives. It helps her feel a little more connected to the world she can only watch.

When TIPPIE's work leads her to David, a young man with a haunted past and information that The Facility wants, TIPPIE uses her skills to earn his trust. The silent girl beneath the surface knows that TIPPIE is only going to hurt him, but she can't help but feel for him. Those feelings only grow, but she knows all too well that TIPPIE's work will soon come to an end.
