Save the Immortal

Спасти бессмертного

Also known as Возвращение Мендыша, Spasti bessmertnogo

A 20-year-old extreme sports blogger lives as if he's immortal. But he suddenly finds himself trapped in a mysterious time loop with no escape. Only a soldier who died 80 years ago can save him—but only after a young man from the future helps the soldier achieve immortality.
