The Copy is Incorrect

When a doppelgänger copies a person, the original dies. This is exactly what happened to Moscow high school student Zhenya. After Zhenya's death, his girlfriend Vera dedicated her life to working at Department D - a law enforcement agency that protects people from doppelgängers.

Fifteen years later, the investigation of another D-victim - an unknown man found in a park - changes her life forever.
