A mindless comedy film which starts with the kidnapping of two grooms on their wedding day by the brides and somehow ends with a spoof on Veerappan. Two unattractive grooms are married to two sisters. The guys get henpecked and they don't have a happy marriage. Enter Shakalaka Baby (Roja) who attracts both the grooms (Vivek and Vadivelu) and their father in law (Manivannan). Then she moves into their house, claiming she is pregnant but she does not know who the father is. Then there is a side track with Ramki who is an escaped convict. Another romantic sidetrack with Udhaya (Roja's brother) and Ramki's sister. To change his daughters' behaviour towards their husbands, Manivannan acts like he is dead. What transpires later forms the crux of the story.
