Oru Kuppai Kathai opens with Kumar, a man who works as a trash collector, approaching cops and confessing that he has committed a murder. The story then moves ahead in flashbacks. After several rejections, Kumar (National Award-winning choreographer Dhinesh Master, in his debut film as a hero) finds a life partner in Poongodi (Manisha Yadav) and the wedding is fixed. But, there’s a little lock here - she believes he works as a clerk, though her parents are aware of the truth. When she finds out the truth, she’s dejected and distances herself from him. And soon, finding comfort in their neighbor Arjun’s (Sujo Mathew) company, she elopes with him and her newborn. How this incident affects Kumar and his family forms the crux of the story.
