Ryuzaki, an editor of Muscle Magazine, which features photographs of men with sculpted bodies, becomes involved with a man named Kitami; their affair soon becomes dominated by sadomasochistic games, with a horrid result. Jump ahead one year, Ryuzaki is released from jail and goes in search of Kitami, perhaps to make amends.
