Madhiazhagan is a successful project manager at a leading property promoters' firm. He is happily wedded to Vasuki, and they have a five-year-old daughter named Pavi. A posh house, a heftily paying job, a highly appreciative and supportive boss, and a happy family - Madhi's life is a far-fetched dream to most people in this era. However, all changes one day, when a man requests to be dropped en route, as Madhi and Vasu set out on a pleasant weekend. The mysterious stranger pulls out a pistol and begins to threaten the couple to bend to his wishes, holding Pavi as a hostage. The day starts with the stranger forcing the couple to draw out all the money Madhi has to the last penny and then setting it all on fire. Next, he makes Madhi lose his career by leaking the top secrets of his company, which were entrusted to him, to their competitor. The day goes on with more gimmicks by the stranger, while the couple is cornered into doing it all for their daughter's life. For the same reason, they also refrain from filing a complaint with the police, even though they are tantalizingly close to their target. While this seems endless, how they figure a way out of the mess, with a completely unexpected twist in the end, forms the rest of the story.
