Chinese scholarship student Wei travels to New Zealand to study medical research at a prestigious university. Shy, introverted, and with a hidden genetic mole on her face, Wei is shunned by her cousin Angela, a social butterfly, and her glamorous friends. Determined to change her fate, Wei immerses herself in research on her late father, working on a revolutionary skin graft procedure that could cure her deformity. As her experiments take a dark turn, she becomes increasingly dangerous and paranoid, willing to eliminate anyone who threatens her secret.
