Lawyer Gordeev, at the request of a young lady, takes over the defense of a young man accused of murder. But it turns out that according to one version, this man is a ruthless killer, and according to another, he was cleverly framed. In order to prove innocence, the real criminal must be found. But those around the young lady are making every effort to nullify the lawyer’s actions. And this continues until the Gloria agency with its private investigators, the Moscow Criminal Investigation Department and the Prosecutor General's Office come to his aid.
