Do It - One!

Gavrilov is conscripted into the Soviet Armed Forces. At the recruitment station, Sergeant Shipov shoves him during a routine check, and Gavrilov refuses to stay silent. He demands an apology, and the heated exchange sows a personal feud that colors their future interactions.

Shipov learns Gavrilov will serve in the Naval Infantry and convinces a Marines officer to transfer Gavrilov's file to his own unit by claiming Gavrilov is his countryman. The officer approves, and Gavrilov is reassigned to a motorized infantry regiment where Shipov serves. The move removes Gavrilov from the unit he expected to join and seeds distrust.

Gavrilov arrives at the motorized infantry unit where hazing is already rampant. The 'grandfathers' force recruits to perform chores, mock them, and steal money from them at night. Shipov lays out the 'main points' of hazing and pushes the younger soldiers to obey brute force.

In the brutal environment, Gavrilov meets Ivan Botsu and the two quickly become friends. They begin to rely on each other as they navigate the hazing and the hostile unit culture. Their camaraderie becomes a small anchor amid the brutality.

During a skirmish in the dining hall, Sergeant Stepanov defends Gavrilov and other recruits from hazing. Shipov threatens Stepanov with a disciplinary battalion if he continues to interfere. The tension between Shipov and Stepanov grows as the harassment persists.

The grandfathers order Botsu to count the days before demobilization, attempting to humiliate him. Botsu refuses, and Yefreytor Kabanov steals money and plants it in Botsu's tunic as a provocation. Shipov exposes the money during inspection, turning the others against Botsu.

That night, several hazing 'skulls' grab Ivan and drag him into the boiler room for punishment. Stepanov witnesses the scene but remains passive due to Shipov's threats. The assault marks a turning point in the unit's brutality.

Gavrilov returns to the barracks to find his friend missing and sense something is wrong. He tries to reach Ivan and ends up in the boiler room, where he himself is beaten by the assailants. The escalation of violence tightens the grip of fear over the recruits.

Sergeant Shipov arrives and orders everyone to disperse, ending the direct confrontation for now. Botsu, overwhelmed by the abuse and humiliation, attempts to commit suicide, but Gavrilov stops him. The incident exposes the depth of desperation within the unit.

Realizing there is no easy way out, Gavrilov steals a PK machine gun from the weapons cabinet. An alarm is raised as guards mobilize. He forces the 'grandfathers' to do push-ups, and orders Shipov to do them faster than anyone else.

The guard outside the boiler room breaks in as the alarm spreads. Gavrilov places the machine gun on the floor and moves toward the exit to avoid a fatal confrontation. The scene ends with Gavrilov escaping the immediate danger, leaving the unit in chaotic tension.

The events close on an unresolved note, with Gavrilov having taken a drastic stand against the hazing system. The outcome for him and the unit remains uncertain, highlighting the high personal cost of resisting abuse in a corrupt system.
