Major Grom: Plague Doctor (2021) Ending Explained – Final Scene & Meaning

Sergei Razumovsky becomes the Plague Doctor due to severe childhood trauma from bullying and violence as an orphan, which gave him dissociative identity disorder. His darker personality emerges after his friend Oleg dies in Syria, fueling his belief that the city's corruption and inequality can only be fixed through extreme measures. He sees himself as a judge and executioner who must purge the corrupt system, even if it means murder and arson.

Foreshadowing: Earlier scenes show Sergei as a successful tech billionaire, but hints of his traumatic past and obsession with justice emerge through his interactions with Grom.

Oleg's death represents the final breaking point for Sergei's fragile mental state.

The ending emphasizes that true justice requires understanding and morality, not revenge. The film warns against taking justice into one's own hands, illustrating that even those with good intentions, driven by trauma or hatred, can become monsters. Grom's victory comes from rejecting violence and choosing law and morality, aligning with Dostoevsky's idea that death only leads to more chaos.
