'Nina' is a short drama about an eight-year old girl named Nina who, because of mainstream depictions of women and her diet-crazed mother, is becoming increasingly self-conscious about the way she looks. When a boy at school kisses every girl but her, Nina takes actions into her own hands and starts a dangerous habit that could ruin her.
