A common man named Kumaran kidnaps the Chief Minister of Tamil Nadu, Yogeeswaran, at a private old age home event in Chennai. The news goes viral, and everyone from the local to the central cabinet starts taking the issue personally. Home Minister Thillainayagam appoints Santhanapandian, the Police Commissioner of Tirunelveli, to rescue Yogeeswaran. Santhanapandian questions Bala, a minister's son who was discovered unconscious at the scene of the kidnapping. Bala tells that he and Kumaran had become friends when Kumaran had saved him from a group of thugs, but they are shocked to see that they both of them love the same girl - Priyadharshini. Bala also reveals that Kumaran willingly allowed him to pursue his relationship with Priyadharshini in exchange for making arrangements for Yogeeswaran to attend the old age home event. Meanwhile, as Santhanapandian and his deputy, ACP Arivazhagan, strive to get clues about Kumaran, Kumaran explains to Yogeeswaran his motive for kidnapping him. Kumaran was an orphan, but due to the efforts of an honest politician named Kumaraswamy, who had sponsored him, he got a good education and became a journalist with the News7 TV channel. When he went to Kumaraswamy's house to thank him for his contribution to his life, he found out that Kumaraswamy had gone missing for many days. On further investigation, he learned that Kumaraswamy had been buried alive by Thillainayagam and his sons Kishore and Prathap. Thillainayagam had contested against Kumaraswamy in the last election and had defeated him by rigging the vote, which forced Kumaraswamy to file a case against him and demand a recount. When Kumaraswamy refused to withdraw the case against him, Thillainayagam and his sons buried him alive. Kumaran then filed a case against Thillainayagam and asked Kumaraswamy's intellectually disabled son, also named Kumaran, who was unaware that his father had been killed, to give the statement to the police inspector. However, the police inspector was Thillainayagam's aide and informed him about Kumaran. Thillainayagam's sons then took Kumaran on a bus and pushed him out en route. He was then run over by a lorry and died. In order to avenge the deaths of Kumaraswamy and Kumaran, Kumaran hatched a plan with Priyadharshini and Bala to kidnap Yogeeswaran in order to expose Thillainayagam slowly through false media reports based on false replies by Bala while being interrogated by the police. In the process, Thillainayagam's sons are taken into questioning. After being tortured, they eventually give in and expose Thillainayagam as Kumaraswamy's murderer, even giving them the location in Thillainayagam's lawn where Kumaraswamy was buried. Thillainayagam is arrested, and Kumaran releases Yogeeswaran. Kumaran also escapes from his hideout and poses as a journalist, while Yogeeswaran says that he cannot identify the kidnapper. Even Santhanapandian gives up on pursuing the kidnapper as the latter had kidnapped Yogeeswaran with good intentions.

Following the success of Ko directed by K. V. Anand, the producers had floated the idea of a potential sequel with pre-production work beginning on a follow-up film featuring co-producer James in the lead role. The film, however, failed to take off and in April 2015, Elred Kumar announced that he would be producing Ko 2 and that the new venture would be made by an entirely different team. New actors and technicians were added to the team to replace those involved in the original, with Sarath announced as the director. Bobby Simha and Nikki Galrani were revealed to be the lead actors, while it was announced that Prakash Raj would play the role of a Chief Minister. Leon James, who made his debut with Kanchana 2, was signed on to compose the film's score and soundtrack. In June 2015, the team released a motion poster and announced that the film was 50% complete.
Soundtrack
The film's score and soundtrack was composed by Leon James, in his first solo venture after previously working on two songs on Kanchana 2 alongside three other composers.
