Morozov (tv-series, 2020)

Nikolay Morozov has been both a revolutionary and a terrorist in his long life. Sentenced to a lifetime of hard labour, he spent 30 years in a tsarist prison. His hair had long turned grey by the time the Second World War broke out, but when he realised his country needed him he volunteered for the army. Nikolay was 87 at the time.
