Thrice having failed in his examinations in Calcutta, Kedar moves down west-to stay with his uncle and continue his studies there. His uncle, Paresh Babu, is a well-known lawyer. His family consists of his wife Manorama, eldest son Anil, daughter-in-law Chanchala and his youngest son Santu.
Kshitindra Babu, a retired Judge, lives close by. His two daughters-Saraswati and Bina are poles apart in temperament. Saraswati- hard, tough and sombre, is exceptionally brilliant in studies. Bina, mild, mellow, coy, is a sweet tempered girl. She knows, her marriage with Santu has been settled in childhood. Naturally her romantic interlude with Santu continues in blush and bloom. But Saraswati suffers from no such inhibitions. Her military attitude works as a scarecrow to every young boy.
In the meantime, Kedar appears on the scene. Bhambal, the leader of the boys in the locality at the very first sight of his disheveled, innocent and simple look, takes him to be a simpleton, who would provide a vulnerable prey to their game of mischievous fun.
Began Bhambal's fun-play, as ruthless as foul. Kedar does not understand all these. He believes Bhambal to be his best well-wisher.
One day Bhambal takes Kedar to Saraswati's house, almost by force, introducing Kedar, in his usual jest, as the University's well-known first boy. Kedar tries to protest, bu t the ever alert Bhambal instantly holds hi m. This favour ably attracts Saraswati towards Kedar. And Kedar? With Saraswati before his eyes, Kedar is charmed, wonder-struck.
This spells the history of first love in Saraswati's life, and a first love in Kedar's life as well. Within his mind, he weaves the rainbow of dream. Bhambal watches everything. And, at the opportune time, he sends art anonymous letter to Saraswati, disclosing everything about Kedar.
Saraswati is benumbed. Hit at the weakest point, she erupts like a volcano hurling insults upon insults, which crushes Kedar into pieces. Kedar accepts all humiliations and insults. What worries him now, is how to get far, far away from Saraswati's life.
But, ultimately one does not always get what he desires. Playing ruthless fun with Kedar, Bhambal suddertly discovers,-however, clever and cunning he may think himself to be, he, infact, as a man, has lost to Kedar. This i nnocent and simple boy has taught him a lesson.
And so, Bhambal turns the dice-board he has outlined himself, upside down. Because, the wisdom that he must have to be a man in the real sense, dawns upon him.
