Aino and Yu Xing are two best friends and two working fine artists. Competition is as natural as intimacy between the two, but their relationship may be heading toward a breaking point. Citric Acid is a platonic romantic film that explores artists and their practices using a fusion of narrative, documentary and art film with subtle political elements.
