One day while inspecting a puncture on the roadside he sees and almost catches the person who put the nails , but misses. After the scuffle Ramendran finds his wallet with a childhood photo in it but couldn't identify him. Due to all this mishaps Ramendran is forced to go on leave. Meanwhile his sister Swathi is in love with a young man named Jithu who is unemployed and is hopeful of an upcoming interview to Dubai. Jithu could not land the job as well seems to be shocked to realize Ramendran is Swathi's brother,which he was not aware till now. As the family starts to look for a suitable groom for Swathi, they plot a plan and ask Jithu to come home with the proposal as if in an arranged marriage. Everything goes well until Swathi's family visit Jithu's home and Ramendran finds old photos of him. Ramendran confronts Jithu , and he confesses for keeping spikes. On the day of his interview, Jithu had parked bike infront of a tea shop, and Ramendran while chasing a runaway accused (Sreenath bhasi) , had taken his bike, and in the heat of the moment leave it on the roadside ,fallen. All of his certificates was soiled and hence to take revenge started to keep spikes for Ramendran's vehicle. If Ramendran makes Jithu do many petty things like making two self goals in the local football tournament, beg on the street etc, if Jithu wanted to marry Swathi . Jithu does everything but at last Ramendran would still say no to their marriage.
