The TV series "Liniya zashchity" tells the story of the everyday life of the brilliant lawyer Andrey Zimogorov, who is not accustomed to losing cases. Unlike his colleagues, he is interested not only in the well-being of his clients, but also in their personalities. Andrey takes on a case only if he sincerely believes in the innocence of the person, and he often notices details that the investigation ignores. His latest client is a young man accused of murdering his own father and his new partner.
