<P> When Ganesh blackmails Vasanth about his video with Anitha, he really doesn't care much about it . So Ganesh blackmails him with Roopala's nude video instead and Vasanth agrees to give money . Bharath follows Vasanth as he goes to Ganesh and a fight ensues between them where Anitha and Ganesh are killed . Then Bharath tells Vasanth that the entire plan to extort money from him was made by his wife Roopala . She wanted to separate from Vasanth because of his abusive behavior but she also wanted to get a lot of money from him . So she approached Anitha and Ganesh to help her make a compromising video of Vasanth and blackmail him and that she would pay them for their work . Ganesh being a big time conman, wanted to double cross Roopala's plan and take the whole money for himself . In order to tackle Roopala, he makes a nude video of her with Anitha's help and shuts her off . Because of her inability to act against both Vasanth and Ganesh, she tries to commit suicide when Bharath and Suseela save her . </P> <P> In a turn of events, Ganesh and Anitha alone plan to join together and leave Maya out so that the number of shares will just be two . Maya comes to know of this and when she threatens them, Ganesh kills her and gets rid off her once and for all . It is during this time when all four men - Bharath, Murugesan, Narain and Vasanth coincidentally enter the scene of crime and become suspects unwittingly . </P> <P> Roopala and Vasanth are arrested for the whole conspiracy and Bharath is released and he marries Suseela . It is here that a major twist arrives in the form of writer Vyjayanthi who has been following Maya's murder closely . She calls Bharath requesting his permission to write a book based on this event and tells that she made few changes in the plot . Bharath is shocked by that and Vyjayanthi narrates the changed plot where, in his desperate desire for Suseela, Ganesh films her also nude and threatens her . When Bharath comes to know of this in addition to Roopala's video, he decides to confront Ganesh and erase both the videos . Meanwhile, Maya comes to know that Ganesh is after Suseela when he is already seeing Anitha, so she also does her part in threatening Ganesh to split the shares into three instead of two and if he fails to do so, she will tell Anitha about Suseela . When Bharath and Suseela go to Ganesh's house to erase the videos, Maya tries to attack Bharath, and Suseela ends up killing Maya . They erase the videos and leave the crime scene that day . When Bharath finds that Murugesan had taken the murder weapon by mistake, he gets it from him and plants it in Ganesh's car and frames him for Maya's murder . This is Vyjayanthi's version of the plot but Bharath refuses to agree to it and requests her to find an alternative . Later, it is shown that when Bharath visits Vyjayanthi, he finds that she is also murdered, implying that Vyjayanthi's version of the story may be true and it is left to the audience as to who is Vyjayanthi's murderer . </P> <Ul> <Li> Arulnithi as Bharath </Li> <Li> Ajmal as Ganesh </Li> <Li> Mahima Nambiar as Suseela </Li> <Li> Vidya Pradeep as Anitha </Li> <Li> Chaya Singh as Roopala </Li> <Li> Suja Varunee as Maya </Li> <Li> Anandaraj as Murugesan </Li> <Li> John Vijay as Vasanth </Li> <Li> Lakshmy Ramakrishnan as Writer Vyjayanthi </Li> <Li> Aadukalam Naren as Narain Vaidyanathan </Li> <Li> Achyuth Kumar </Li> <Li> Abhinayashree </Li> <Li> Raghul David </Li> <Li> Ravi Venkatraman </Li> </Ul>
