James (Sathyaraj), a middle-aged man working at a US-based call centre company's night shift in Chennai. One day, on his way back from night shift, James witnesses a murder in the local train. The victim is revealed to be a harbour union leader, Krishnamoorthy (Ajay Rathnam), leaving James as the only eyewitness. Inspector Soundarapandian (Raj Kapoor) interrogates James about the murderer, and he promises the police to identify the murderer. An informer, Aishwarya (Sunitha Varma), is summoned by Inspector Soundarapandian to crack the case. Both Aishwarya and James are asked to stay at the neighbour's house of Krishnamoorthy's family as husband & wife, a drama set up by the inspector to nab the murderer. Soon, they became close with the family and their three daughters. Things get intriguing when it is shown that James himself is the murderer, and he kills Krishnamoorthy's father this time.
Parallel narration is the comedy track of White (Vadivelu), who is a friend of James.
Through the flashback, it was shown that James's real name is Balamurugan. Actually, it was Krishnarmoorthy's family that killed James's Parents several years ago. So, back in the present, James is on a killing spree to avenge this entire family. How James managed to pull this off and find his biological sister among the three girls forms the rest of the story.
