Thiru (Vijay Sethupathi) is a small-time crook, who, along with his sidekick Super (Surya Vijay Sethupathi), steals money and valuables from various people. Thiru's uncle keeps trying to get him to sell the house to earn money, but Thiru repeatedly refuses, leading to some comedy situations. Venba (Anjali) is a loud-talking girl who keeps rejecting all the grooms that her uncle chooses for her, keeping them both at loggerheads. Thiru meets Venba one day and falls in love. Initially, she does not like him, but over time, she reciprocates.

A few days later, she goes to Malaysia for work to earn some money, before which Thiru marries her. She promises Thiru that she will meet him in two days. However, Thiru receives a call from her where she says she needs five lakhs urgently and learns that her uncle had sold her off to the skin trade after that receiving a lump sum of money; she further requests Thiru to come to Thailand to rescue her. Anxious, Thiru finally agrees to sell the house and gets two passports for himself (under the name Hakim Sindhubaadh) and Super (under the name Milan Bharti), and they leave for Thailand.

On the way, they meet a passenger (Vivek Prasanna) who is going to the same place as them to see his daughter. However, on the way, they get in trouble with the Malaysian police and to rescue Venba, Thiru agrees to steal some shields for the law from Ling's (Linga) house, a dreaded criminal and second hand for Chang, a Malaysian don. However, he gets caught by Ling and, in a bid to escape, jumps off a cliff while spitting at Ling. Ling swears revenge.

Thiru and Super engage in a cat-and-mouse chase with Ling's henchmen. Meanwhile, because Thiru does not arrive on time, Venba tries to escape but is caught and sent to Ling, which is revealed to Thiru by the police officer. He shows that the reason behind stealing the shields was to gather evidence against Ling. Thiru kills Chang and blows up Ling's house, infuriating Ling further. Finally, Thiru rescues all the girls from the skin trade, kills Ling, and returns to his home with Venba.
