Jitu and Guddu (both 28 years old) have been good friends since childhood. They both now work at the same company. Guddu's girlfriend, Saraswati, is also employed there, but Jitu and Saraswati are at odds. Saraswati is a cunning woman who always prioritizes her own interests, which is why she stays close to her boss, who enjoys the company of women and likes to have fun with them. Jitu constantly tries to convince Guddu that Saraswati is not the right girl for him, but Guddu is deeply in love with her. The boss dislikes Jitu and often insults him in front of everyone for trivial reasons. Both Jitu and Guddu are frustrated with their boss. In general, Jitu is very smart, whileGuddu is the complete opposite. One day, the boss gives Jitu extra work to keep him occupied in the office overnight, so Jitu can't attend his birthday party with friends. Despite his reluctance, Jitu stays and works alone. Before midnight, however, Guddu arrives at the office to surprise Jitu with a birthday cake, alcohol, and other intoxicants. They spend the night indulging in the party and, due to the effects of the substances, begin behaving strangely, talking about absurd things, including zombies. Exhausted, they eventually fall asleep. They remain unconscious for a whole day due to the intoxication. During this time, a deadly virus spreads across the country through an en ergy drink called ZORR. When they finally wake up, the office security guard, Vikrant, informs them about the outbreak. Jitu and Guddu are stunned. Looking out of the window, they are shocked to see that everyone near the building has turned into zombies and are roaming around. Vikrant, who has been fighting off zombies, warns them that to survive, they need to gather food and find a safe place to hide since the zombies have no specific pattern of attack. Amid all this chaos, Guddu's foolish ac tions attract the zombies, and the three of them are attacked. Somehow, they manage to escape. Suddenly, Guddu hears Saraswati's voice. Without thinking, he rushes to the parking area to save her. There, he sees a car surrounded by zombies, with Saraswati trapped inside. Jitu, Vikrant, andGuddu manage to save her from the zombies, only to discover that the boss is also in the car. Upon seeing him, Jitulashes out, and when Saraswati tries to shift the blame onto the boss, a heated argument ensues between them. At that moment, Rohan and Needhi arrive after escaping the Zombies. Needhi and Jitu are both surprised to see each other because there was a time when they were in love, but noone else present is aware of this fact. Rohan in troduces himself and Needhi to the others. When they return to the office floor, they discover that Vikrant has been bitten by the zombies. After Vikrant turns into a zombie and tries to attack them, Guddu, in an attempt to save himself, bashes Vikrant's head with a beer bottle. When the beer spills over Vikrant's face, he suddenly freezes like a statue. They seize the opportunity to escape and reach another floor, where they meet Gaurishankar, a saintly man from Kashi (U.P.) who speaks with a clearHindi accent. The group devises a plan to reach the parking area and escape in their boss's car. However, Rohan secretly makes a different plan: he intends to leave Jitu behind with the zombies and escape with everyone else. Since Jitu and Rohan have been at odds, the boss has been supporting Rohan from the beginning. According to the plan, Rohan abandons Jitu and escapes with the others in the car, but the car suddenly stalls, and they all become surrounded by zombies, including Jitu. Suddenly, Durga, an army officer, arrives to rescue them. Gaurishankar, upon seeing Durga, becomes infatuated and falls in love with her. With Durga's help, they safely return to the building. The Indian Army is working tirelessly to rescue people and evacuate them to safety. The army plans to send a helicopter to rescue the group, but they need to reach the rooftop first. During the night, however, many zombies attack, and one by one, the group falls victim to them. By morning, the helicopter hovers above the rooftop, but by then, only Jitu, Needhi, and the boss have survived. In the end, the boss sacrifices his life to save Jitu and Needhi. The next morning, Guddu is found alive, and to his surprise, not a single zombie had touched him. Guddu easily escapes from the zombies.
