Story…Kathiravan (Vijay Sethupathi) is a rowdy who works for a local area councillor (G. M. Sundar). His only aim in life is to own a bar of his own. He had just been released from prison after serving a five-year sentence for taking the blame for a crime he did not commit on the orders of the councillor. Kathir did the deed on the promise that his status within the councillor’s gang will be elevated once he is released, but the promise was reneged.

Meanwhile, a young Villupuram-based engineering graduate Yazhini Bakthirajan (Madonna Sebastian), leaves for Chennai against her parents’ wishes to pursue a career in the IT sector. When the company she works for shuts down suddenly five months later, she faces financial hardship and is forced to move into a low-cost housing colony while searching for a new job. Her neighbour is Kathir. Though both of them dislike each other in the beginning, they gradually warm up to each other despite their different backgrounds and become a sort of support system for one another.
