Set on the background of a political turmoil of Naxalite era in Bengal, Pratidwandi is the story of rampant corruption and unemployment. In the dingy socio-political panorama of late 1960s, Pratidwandi depicts the story of Siddhartha, a modern educated man gradually becoming the prey of tumultuous socio-political condition. Having experienced the better days, Siddhartha had not any knowledge about what poverty is. It was after the death of his father and when the tea estates all are lost, Siddhartha, being the eldest son, is entitled to carry the responsibility of the whole family. Thus he came in close contact in the huge concourse of frustrated young generation, who are jobless in spite of being educated. Inflicted with cynic ennui, Siddhartha was mortified, when his younger sister had to go out to earn money in the presence of his elder brother. Also tormented by the involvement of his brother in the Naxalite activities, Siddhartha became the victim of his own nuisance. He could neither align himself with his revolutionary activist brother, or career-oriented sister. His sister's outrageous behavior develops his strong detestation against the women. Humiliated with his own failure, Siddhartha was caught in a sense of identity crisis. However, being an optimistic social prophet, Sunil Gangopadhya, brings in Pratidwandi, a recurrent motif of romanticism, marked with a glimpse of optimism. The call of a strange bird, while he was writing letter to his beloved in Balurghat, preoccupied Siddhartha with the memory of the childhood days even in his ennui. In the concluding part of the novel Pratidwandi, the optimistic note is explicit enough, when, in the chants of funeral procession, Siddhartha can feel the rebirth of childhood tranquility, out of the dark, monotonous society.
Pratidwandi means a competitor. Here Siddhartha, representing the entire young generation of dreary society of post modernism, where the young man like him stands as a victim of the socio-political turmoil. The title Pratidwandi signifies the rebellion of Siddhartha against the unfeeling bureaucracy and he became the "Pratidwandi" or competitor of all the victims of bureaucracy, represented by his sister. The title" Pratidwandi" aptly justifies the very spirit of the novel, concerning the frustration and cynicism and finally a foretaste of optimism, of the protagonist Siddhartha, the replica of his generation.
