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.
