Major Grom: Plague Doctor

Police major Igor Grom embarks on a daring chase after three bank robbers dressed as villainous hockey players from the popular Soviet cartoon Puck! Puck!. Despite successfully apprehending them, Grom's pursuit leads to substantial property damage, and he faces reprimand from his superior, Colonel General Fedor Prokopenko.

The trial begins for Kirill Grechkin, a wealthy young man accused of fatally hitting a girl with his car. Shockingly, despite overwhelming evidence against him, Grechkin is acquitted, leaving the victim's brother, Lyosha Makarov, deeply suspicious of the court's integrity.

Following the court's decision, videos featuring a masked vigilante known as the Plague Doctor begin to circulate online. This enigmatic figure, armed with explosive devices and a flamethrower, vows to purge the city of criminals, growing a cult following among the disillusioned citizens.

The Plague Doctor executes Kirill Grechkin by setting his car ablaze, delivering a brutal message about justice to the corrupt. This act of vengeance has a profound effect on those deeply affected by Grechkin's reckless behavior, especially his victim's family.

Oleg Volkov, a childhood friend of the girl killed by Grechkin, admits to Sergei Razumovsky that he is the Plague Doctor. Despite being shocked and distressed by this revelation, Razumovsky grapples with whether to report Oleg to the authorities.

Having witnessed the murder, Grom sets out to investigate the Plague Doctor's identity. However, he faces obstacles when the FSB officer Evgeny Strelkov removes him from the case, redirecting him to handle a low-profile theft of refrigerators.

During his investigation, Grom rescues a young woman named Yulia Pchyolkina from thugs. Unbeknownst to him, Yulia orchestrated the attack to gain access to Grom and learn more about the Plague Doctor for her blog, entwining her fate with his.

The Plague Doctor's rampage continues as he targets figures like a corrupt bank head and a polluting landfill owner. Each murder fuels the public's mixed sentiments towards him, as many view his actions as justified within the context of rampant corruption.

Grom and his trainee, Dubin, infiltrate a high-profile casino opening where they suspect the Plague Doctor will strike next. Although they face off against the Doctor's followers, the confrontation instead reveals more about the social dynamics at play within St. Petersburg's elite.

Following the botched casino engagement, Grom is forced to resign from the police by Strelkov. Despite this setback, his resolve to uncover the truth about the Plague Doctor only intensifies, igniting a personal mission for justice.

As Grom continues his investigation into the Plague Doctor, he uncovers troubling details about Razumovsky's childhood and his ties to Holt International, a tech company responsible for creating the Doctor's gear. This revelation deepens the intrigue surrounding Razumovsky's true identity.

In a dramatic twist, Grom confronts Razumovsky, suspecting him of donning the Plague Doctor's mask. In the ensuing struggle, Razumovsky's darker side overtakes him, leading to a shocking betrayal that leaves Grom vulnerable and framed for the Doctor's crimes.

With the help of Dubin and Pchyolkina, Grom manages to escape custody. As he delves deeper into the Plague Doctor's plan for social cleansing, the trio prepares for a final confrontation with Razumovsky amidst the chaos in the city.

In a fierce battle, Grom faces Razumovsky, who reveals his intentions for a new society through violence. The tide turns as Dubin and Pchyolkina intervene, leading to Razumovsky's capture and a public revelation of his malevolent aspirations.

As the city begins to calm down from the chaos, Grom finds solace in his new friendships and reflects on the events that transpired. Meanwhile, Razumovsky is institutionalized, hinting that his dark side may still be alive, and Oleg Volkov is alive elsewhere, watching over his friend's downfall.
