Cryptomorphs have appeared among us - creatures with dangerous paranormal abilities. Obeying a mysterious impulse, they now pose a mortal threat to other people, who create a special organization to fight cryptomorphs - the Department of Countermeasures. But are these creatures really that dangerous? And what goals are they really pursuing? Runa Lark is called upon to answer these questions: having joined the Department, the determined girl becomes the partner of Eric Raynar, a young agent who is famous not only for his effectiveness in exterminating cryptomorphs, but also for his disgusting character. The heroes will have to work together, overcoming conflicting feelings, because Runa and Eric soon realize that each of them keeps secrets that can destroy each other's lives.
