Gopi Krishnan, his wife, Rajalakshmi, and daughter, Dhanya, are enjoying their moments at
Kutralam Waterfalls. Soon it is revealed that Gopi Krishnan is a corrupt assistant
town planner using a government vehicle to come on holiday in
Tamil Nadu during his duty hours. As his driver takes him back to his station in
Kerala, he has an altercation with Sukumaran whose identity and profession are not yet revealed. Sukumaran lives in a rented flat with his daughter. There is also a subplot involving the
child custody battle between Nandhakumar and his wife, Meera. Later, Sukumaran is seen at the town planning office trying to get a building permit, and meets Vasudevan, who is also having difficulty with building permits. In reality, Sukumaran is in disguise and is actually a
vigilance officer named Nandhakumar trying to arrest Gopi Krishnan in a corruption case. Nandhakumar makes three attempts to get evidence against Gopi Krishnan. The first two failed because Nandhakumar's subordinate, Sunny, leaked the plans to Gopi Krishnan. Vasudevan commits suicide after the first failure. Finally, after catching Sunny, the third attempt succeeds, though there is confusion over the evidence, and some thugs attempt to murder Gopi Krishnan while he is in police custody. However, Nandhakumar loses his court case against his wife and has to give up his daughter. Faced with the collapse of his corrupt life, Gopi Krishnan agrees to work with Nandhakumar to root out corrupt
real estate developers. Meera returns Nandhakumar's daughter to him, saying that she could not handle her crying for her father all the time. ==Cast==
