Rick Stone is the world's biggest action star but unfortunately, he is also the prime suspect in his wife's death. He must enlist the help of a conniving tabloid reporter named Dana Fields and the trust of his mistress Stephanie to try and clear his name.
Despite qualifying for armed force, Karthik ('Jayam ' Ravi) prefers to be a traffic cop in Ooty as he believes that such a no risky job would help him get enough time to look after his cute little sister Vidhya (Baby Anikha). Karthik also has a short lived one side love story with Renu (Lakshmi Menon), who is a doctor. When a hazardous chemical in the nearby industry gets leaked, a dog consumes it and turns into a zombie. As the dog bites a watchman, he too becomes a zombie and eventually, the virus spreads rapidly across the town. Can Karthik save his sister and the city ?
