On the night of their high school graduation, three delinquents decide to exchange their darkest, most unspeakable secret.
Jin-Hua and Jin-Tien are twin sisters. Quiet and shy Jin-tien is an animal trainer at an aquarium. When her sister suddenly goes missing, Jin-tien must stand for her in a magic show. While inside the box, she is confronted with the childhood Jin-tien, Jin-hua and their mother. A very lyrical film about memories of loved ones.
Elder sister, Spring, seeks her origins before heading to university, Autumn, the mother, grapples with conceiving a child through artificial insemination, Summer, the younger brother, tries to engage with a paternal figure he barely knows just before his military service, and Winter, the father, desperately tries to change his fate as problems mount up.
