The story opens with a wedding in progress, where the bride waits for her groom, the groom Guru Chaams is missing, and the anxious bride decides to call Guru’s friend Billa Vinay Rai, who doesn’t know Guru’s location. This triggers a flashback that sets the stage for the film’s main caper.
In the flashback, Billa, Ranga [Sathyan Sivakumar], and Kochadaiyaan [Aravind Akash]—three close friends who are trying to escape mounting life troubles—decide to flee into a carefree bachelor existence. Before they depart, they invite their good friend Guru [Chaams] to join them, and despite the fact that Guru is about to wed, he agrees to tag along. The quartet swears an oath to keep their new bachelor life a secret from their wives, a pact that sustains their misadventures as the story unfolds.
Their first stop is the city of Bangalore, where they reconnect with Charles [Premji Amaran], a college mate who has since become a multimillionaire. Charles is initially wary—after all, they used to tease him in college—but his change of heart leads him to help them realize their plan by taking them to a party. It’s at this party that they first lay eyes on Sanjana [Raai Laxmi], a striking model who dances with them and sparks their interest. Afterward, Charles brings them to a private condominium where they set up temporary residence and try to win Sanjana’s affection, each of the four using their own clever schemes to impress her.
The party high soon gives way to more complicated schemes as the group continues pursuing Sanjana. After their time with her, Guru decides to throw a bachelor party of his own as he prepares to get married. Yet the next day arrives with trouble: Guru is missing again, and the three remaining friends—Billa [Vinay Rai], Ranga [Sathyan Sivakumar], and Kochadaiyaan [Aravind Akash]—get drunk while wearing police uniforms. They are detained by DSP Balram Naidu [K. S. Ravikumar], who advises them to value their wives and not abandon them. This encounter leads to a renewed determination to find Guru, but their search takes a dangerous turn when they are kidnapped and taken to a warehouse.
In a shocking twist, Sanjana [Raai Laxmi] appears—revealing herself as the mastermind behind the whole kidnapping. The men realize they have chased her for love, a pursuit that has been captured on videotape. She price-tags Guru’s release at a staggering sum of Rs. 2 crores, and she threatens to reveal the footage unless her demand is met. The four friends manage to secure the money, hand it over to Sanjana, and flee Bangalore, promising never to cross paths with her again while prioritizing the well-being of their wives.
Back in Chennai, the drama escalates as they rush to arrive in time for Guru’s wedding. Just moments before the ceremony, Apple [Geetha Singh], Billa’s wife, intervenes with a dramatic gambit—threatening everyone with a time bomb strapped to her waist. Billa seeks forgiveness with Apple’s guidance, and the group, along with Charles, escapes the danger and is soon reunited with their wives. The story then follows a continuation of their misadventures, including Charles’s surprising romantic twist—his college teacher becomes his new wife—before the action shifts to future chapters of their escapades.
Throughout these escapades, the film blends humor, camaraderie, and the tension between husbandly duties and the lure of carefree bachelor life, all while the characters continually navigate loyalty, love, and the consequences of keeping secrets. The dynamic between the four friends and their evolving relationships with their partners provides both tension and comic relief, culminating in a narrative that stays true to its light-hearted, slapstick roots while offering moments of warmth and surprising emotional beats.
