What Happens in Thiru Thiru Thuru Thuru: Full Plot Summary

The whole story of Thiru Thiru Thuru Thuru (2009) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

Srinivasan [Mouli] is the owner of a struggling ad agency, trying to pull the business back from the edge of losses by chasing a high-stakes project from a big client, Johnson and Johnson. In a crucial meeting, Arjun [Ajmal Ameer], the art executive and Srinivasan’s trusted right hand, entertains the clients with his energy, but his mischievous spark slightly unsettles the room and dampens the early confidence of the pitch. To salvage the deal, Srinivasan decides to go all-in, funding the ad production himself and taking on full risk, with the tacit understanding that the project will be deemed a success only if everything is executed to perfection.

When the star of the commercial—the baby—falls ill, Arjun and Archana [Rupa Manjari] step in to keep the production on track. They scramble to find a suitable replacement, hoping to avoid delaying the shoot. Arjun locates a cute baby on the street and approaches the mother, who initially refuses the proposal. As the team works to persuade her, the mother is suddenly involved in a serious accident. Arjun quickly arranges for her hospital care, yet in the chaos he also takes the baby to the client to secure a provisional approval, hoping to keep the project alive. Upon returning to the hospital, he discovers that the mother has left the scene, seemingly unconcerned about the child. With a mix of urgency and responsibility, Arjun brings the baby to the police station to seek guidance, and a friend from the police helps them make plans. The trio—Arjun, Archana, and the baby—then returns home where the shoot resumes, but a new hurdle looms.

After the ad is shot, the client demands a written no-objection agreement signed by the baby’s parents within the next three days, a safeguard to prevent future disputes and to ensure compensation for any money already spent if the deal collapses. Faced with this tight deadline, Arjun and Archana begin a dangerous investigation to verify the baby’s true guardians. They uncover that the woman who appeared to be the mother is not the real mother at all but a baby stealer. The search takes them to Pondicherry, where they press for answers and press the woman for the truth. Although she denies the charges, the team uses non-violent pressure to extract critical details about the real parents. The revelation is jarring: the kidnapper and her boyfriend have been scheming for a hefty ransom of twenty lakh rupees, and in a tense turn of events, the baby slips from their clutches and ends up with Arjun.

The plot thickens as the kidnapper shifts gears, trying to pass herself off as the baby’s rightful parent and directing the baby’s real parents to hand over money and arrange a secret pickup at a remote location. Arjun and Archana cross paths with more danger as they arrive at the hidden spot, sense something is amiss, and flee with the child to avoid a confrontation that could end badly. They become trapped in a precarious crossfire among the kidnapper ring, the anxious parents, and the police, adding far more danger and tension to their mission than they anticipated.

As the due date for the agreement closes in, Srinivasan confronts the pressure of failure and reluctantly concedes that the necessary paperwork cannot be produced in time, deciding to withdraw from the project. Yet, in a dramatic reversal, Arjun and Archana arrive with the signed document in hand, and the client’s demand for assurances is finally met. The truth emerges that they were misinterpreted as kidnappers and briefly detained by the authorities; once they explain who they are and reveal the completed ad—featuring the baby—the real parents are relieved and overjoyed to have their child back. The contract is signed, and the project is officially approved, marking a successful turnaround for the agency.

In the end, the ordeal resolves with a note of uplift: the family’s reunion is celebrated, and the work that must have seemed doomed is vindicated. Arjun and Archana, having weathered the chaos and danger together, also find a personal connection that blossoms into romance, offering a hopeful close to a story that tested loyalty, ingenuity, and the limits of trust. The film blends workplace pressure with a high-stakes pursuit of truth, delivering a message about perseverance, ethical boundaries, and the power of partnership in both professional and romantic realms.
