Through a series of intricately composed long takes, Epilepsy exposes the robotic state of students today through the eyes of a young boy. For him, going to school simply means a continuous dose of discipline and punishment from all sides. His education simply means taking what he's given, and any dissent or deviation from the norm is discouraged with force. Even when a girl begins to inspire change in him, will he be able to face a strange, new world that is so different from the one he knows?

Security guard Cheung is a loving father who takes good care of his children. As his kids grow older, they have their own lives and that leaves Chueng feeling lonely. He displaces his fatherly love onto his colleague Sheung's young children instead. This innocent act, however, makes his daughter suspect that Cheung and Sheung are having an affair and a small incident risks being blown out of scale.
