An RPF railway officer named Williams (
Aruldoss) is miffed and frustrated, regarding the fact that the public did not respect the RPF cops. He decides to bring in strict rules and asks his subordinates not to show mercy towards defaulters who make offences and for those who mess up with the railway rules. With the help of his team, he nabs many passengers who violate rules in different ways, which include peeing on railway tracks and travelling on trains without tickets. On the other hand, Sathya (Sachin Mani) is a jobless man who falls in love with a girl named Megala (
Nandita Swetha), who is from a rich family and holds a job for herself. Megala also falls in love with him, which was not tolerated by her father (
Chitra Lakshmanan) and suddenly arranges for a marriage to his daughter. When Sathya gets to know about this, he urgently prepares himself to travel by train from Tambaram to Puducherry in order to convince Megala from the arranged marriage and to marry her, but his dreams were spoiled by Williams, as he was arrested by cops on his way for committing an offence and was taken into custody at the Tambaram railway station. Soon after, he meets prisoners Baskar (
Sendrayan), Kunjitha Badham (
Manobala), Kutti Puli (
Arunraja Kamaraj), Sathish (
Appukutty), and Kodeeswaran (
Mayilsamy) and narrates his love story to them. After being impressed by the story, the prisoners hatch a plan to help Sathya to escape from police custody. == Cast ==
