A tender romance blossoming in Kolkata between law student Ramesh and his friend’s sister Hemnalini, is nipped suddenly when his father sends an urgent and mysterious summons from his village home. There, the dutiful son is ordered to marry Susheela, daughter of a hapless widow. Ramesh refuses, confesses that his heart belongs to another, but finally relents. Hem knows nothing of all this and waits, confident that Ramesh will return soon.
After the wedding Ramesh sets out with his bride on a river boat journey back to Kolkata. On the way a fierce storm arises and the boat capsizes in the churning waters. When Ramesh gains conscience he sees his bride. There is no one else in sight, alive or dead. The two move off, take a train to Kolkata, the bride wondering why they were not going to Kashi, but trusting his judgment implicitly.
In Kolkata Ramesh realizes the mistake he made - having brought with him another woman, Kamla and not his wife Susheela. Will Ramesh reconnect with his first love, search for Kamla's or follow his responsbilities as a husband to Kamla?
