Sri, an engineering graduate, travels to the city to interview for an IT job. He clears the HR interview with Regina Cassandra and celebrates with friends at a bar. This marks the onset of a string of chaotic events in a crowded city.

In a flashback, Sundeep confronts a group of goons who threaten Regina with acid over their past affection. Enraged, Sundeep punches one of the goons to defend Regina. The scene foreshadows the violent loyalties that will unfold later.

Back in the present, the bar thugs recognize Sundeep and hire gang members to beat him. The gang mistakenly attacks Sri instead, beating him, stealing his phone and bag, and tossing his bag into a taxi.

Charle, driving a taxi rented from PKP to treat his sick son, discovers Sri's bag in the taxi along with his certificates. He takes the bag to the police to help recover the missing documents. This sparks a chain reaction that drags various players into the investigation.

Sri wakes up on the street and calls a friend to take him home. He then boards a bus bound for his new job to explain the loss of his academic certificates. The journey marks his attempt to salvage the situation.

Sundeep boards the bus to attend his interview and spots the goon who threatened Regina. He confronts the man and, with his companions, attacks him with acid and makes a quick escape. The incident intertwines the fates of the two men.

Sri is detained by the police after inadvertently passing the acid bottle to Sundeep. A constable later confronts him at a tea stall, where Sri recognizes the informer who gave the instruction, and the constable arrests that person. The misfortune escalates the city-wide tensions.

A gang hatches a plan to kidnap PKP's schoolboy, using a man named Winnings to trick teachers. Five boys named Karthi appear, and one volunteers to go with Winnings to dodge a mathematics test. They abduct a boy but soon realize he is PKP's son, intensifying the stakes.

Sri tells Regina that he has lost his academic certificates, and she agrees to cover for him for a day. The debate over his job continues, and Sundeep waits for his own job interview, adding to the mounting strains in Regina's orbit.

PKP orders his henchmen to hunt down rivals and push for a ₹1 crore ransom. Meanwhile, the police inspector—who is Sundeep's uncle—releases Sundeep, heightening the conflicting loyalties and pressures around Regina and the case.

Sundeep waits for Regina at a bus stop outside her hostel. Regina spots Karthi in a truck and directs Sundeep to take Karthi home. The moment underscores the fragile balance between duty, romance, and danger.

The inspector shoots PKP and aims at Winnings, but Sundeep shoots the inspector in the leg and orders Winnings to take PKP and Karthi to the hospital. The pair then confront the fallout as PKP and his allies head to treatment, ending the dangerous chase with a narrow escape.

Meanwhile, Sri is riding in Charle's taxi when a gang believes they are spying for PKP and stops them. Sri fights back to let Charle escape, and later, Sri's lost certificates are returned to his home address. The days close with a charged sense of unfinished business as new threats loom.

Outside the hospital, Sri and Sundeep speak with their girlfriends and are about to introduce themselves when another gang challenges them. They rush to defend themselves, stepping into one final burst of danger that caps the turbulent tale. The day ends with a wary sense of what comes next.
