Ramesh (Askokan) is an engineer who is hunting for a job and with the help of his friend Babu (Thangavelu) goes to see a wealthy businessman named Laxman for a new project of his. After a song and a comic encounter with Laxman's daughter Geeta (Manimala), he falls in love with her. He also achieves very good success in convincing Geeta's father into starting the project. During a sight visit for the project, his suitcase gets swapped with a similar suitcase of a co-passenger named Mala (Manorama), which is full of money. For this reason Ramesh is detained in a police lock-up. Also Mala is revealed to be part of a criminal gang. When the gang leader, Jumboo, is not able to kill Mala (because he needs a particular diary from her), he instead arranges a dangerous rowdy named Bijua Pakiri (R.S. Manohar)to kill Ramesh within the lock-up.
