Arjun (Silambarasan), an animation artist living in London with his uncle (VTV Ganesh), meets Nisha (Varalaxmi Sarathkumar) in a London pub. She is an aspiring dancer who is living with her aunt Veena (Shobana). After going around together for a day, Nisha proposes a relationship, and Arjun agrees. Arjun hates Nisha attending salsa classes with her friend Mojo as her partner. However, he agrees to marry her.

After their marriage, Nisha makes it clear that she still wants to dance and enter the UK competition "Let's Dance", and make a career for herself. Arjun suddenly discovers that he is, at bottom, a "Pachai Thamizhan" who believes that a woman's place is in the home (preferably the kitchen, but she has the freedom to walk from one room to another if she wants). On the advice of his uncle, he impregnates her, so that she stays away from dancing.
