Rameshan and Jose are best friends coming from similar backgrounds. Both are educated well-groomed lads of more earthy parents. Rameshan's father Paramu Nair is a tea shop owner while Jose's father Varkey is a farmer. Both have sisters waiting to be married off, only being confined by the outrageous demands for dowry. Rameshan is also in love with Rema, daughter of a wealthy landlord Raman Vaidyar, who is hell-bent on marrying off his daughter to a doctor.
While local brokers try to fix up the ladies with suitable men by hook or crook, Rameshan and Jose grow increasingly anxious for jobs. Seeing the success achieved by the local brokers, they decide to get into the marriage broker business after convincing their parents that this would be a winning shot. However, their plan goes bust when the business flops driving them both to desperation again. Meanwhile, Rema gets married off to a doctor Sudakaran as Rameshan fails to find the courage to save her. Rameshan's sister also elopes with the local coconut picker Damodaran after her father reluctantly arranges her marriage with Raman Vaidyar. Though initially enraged, Rameshan reconciles with his sister and Damodaran after realizing that his sister could not have found a better man.
Damodaran advises Rameshan to get rid of his stigmas and join his father's tea shop. Both he and Jose join their father and are able to find better success than with any of their past ventures. Meanwhile, Varkey forms a plan to get Jose married off for a sum of dowry, with which he could marry off his daughter Rosie. They find suitable alliances and the marriage is fixed. However, the happy occasion is clouded by the tragic news of Rema's death. Rema was deeply unhappy with her husband who constantly harassed her and her father for money, despite her father having paid a huge sum of dowry and almost neck up in debt. Rameshan is devastated and ridden by guilt that he could not save her from this terrible fate. Finally the day of the betrothal dawns and both Jose and Rosie take their vows together.
But the happiness is short-lived as Varkey discovers belatedly that the girl's family had not been able to gather the promised dowry. He is furious but even more fearful that this would severely affect Rosie's marriage. On hearing that they would not receive the dowry promptly, Rosie's betrothed and his family immediately break the betrothal. Varkey, mad with anger and grief commands Jose to break off with his betrothed too, which he gallantly refuses. Rameshan pleads desperately with the leaving parties as well as with the church priest and locals to stop and reconsider, as the cancellation of this marriage would devastate Rosie. When no one offers support and hurl more abuses, Rameshan steps forward and asks Jose for Rosie hand in marriage. Despite the difference in faith, Jose and his father are overjoyed at this. At the end Rameshan takes a grateful Rosie's hand in his, while Varkey and Jose look on with joy.
