Eshwar, a 28-year old IT professional, and his pregnant wife, Aathika, rent the top floor of a duplex. S. Ilamparuthi, the Executive Officer of the Kundrathur Town Panchayat, lives on rent on the ground floor with his wife Selvi and daughter Aparna. Despite their contrasting lifestyles, the two families initially get along well until Eshwar buys a new car for his wife to travel in comfortably. Ilamparuthi, who has lived in the duplex for the last ten years and has kept the entire parking space to himself since neither he nor the previous top floor tenants ever owned a car, is uncomfortable with Eshwar's car parked in the parking space. After a few incidents, both begin to fight for rights over the parking space. Ilamparuthi sells his motorbike for a car to ensure that Eshwar does not park his car in the parking space.
Eshwar and Ilamparuthi continue to fight over the parking space, which culminates with Ilamparuthi breaking Eshwar's car window when Eshwar manages to park his car ahead of him. They quarrel in full public view, which escalates when Ilamaparuthi insults Eshwar's mother, causing Eshwar to slap him. Seeking revenge for the slap, Ilamparuthi and his brother-in-law force Aparna to file a false case of harassment against Eshwar. He is arrested, but Aparna, feeling guilty, withdraws the complaint and Eshwar is released. In retribution, Eshwar frames Ilamparuthi for accepting a bribe of , leading to his suspension. Despite Aathika pleading with Eshwar, and Selvi and Aparna begging Ilamparuthi not to escalate their tensions, the duo refuse to budge. Ilamparuthi loosens Eshwar's front tyre, which leads to a near-fatal accident when Eshwar is taking Aathika to hospital for her regular checkup.
Having deduced that Ilamparuthi is responsible, Eshwar wrecks his car in revenge. Fed up with Ilamparuthi's behaviour towards Eshwar, Selvi and Aparna leave him. Eshwar, on Aathika's insistence, decides to move out. He manages to find another home, then meets with Ilamparuthi to inform him of the same and condescendingly asks him to leave them alone. Feeling insulted, Ilamparuthi knocks him out in rage. At this juncture, he finds that Aathika has gone into labour but seemingly does nothing. When Ilamparuthi returns, Eshwar regains consciousness and knocks him out, refusing to listen when Ilamparuthi tries to inform him about his wife's condition.
Eeshwar starts heating Ilamparuthi's mobile phone in a microwave oven and orchestrating a gas leak with the intention of killing him, but when he eventually learns that Ilamparuthi had helped Aathika by driving her to the hospital, where she gave birth, he realises his mistake and switches off the main power supply for the house, averting a major disaster. At the hospital, Eshwar and Ilamparuthi – who has reunited with his family – apologise to each other for what had happened and agree they could have adjusted and handled the parking issue in a matured manner.
Sometime later, both families have vacated the duplex. A broker allows a couple to rent either floor, with one condition being that they must not own a car, to which they agree.
