Escaping captivity doesn't make you free. Subject B and her sister, Subject A, have spent their entire lives inside a secret lab, the victims of cruel experiments by the Professor. Subject A is given the power to read minds and Subject B the ability to melt into liquid form. Together, they use their gifts to escape the lab. On the outside, the sisters take different paths to cope with their pain. Subject A uses her gift to understand human nature, but Subject B is haunted by the lab, and won't trust anyone. As Subject A tries to control the darkness within her sister, Subject B is faced with the choice to forgive the Professor or take her revenge.
