Queer are the ways of Fate. One never can tell what is in store for him toomorrow? The new Bank Manager, Balraj (played by Shekhar), who took over the charge of the Bank's Lucknow branch deemed his transfer a normal rotuines. He being a man of sociable nature soon became friendly with his clients and 'Rangeen' (played by Radha Krishen) his Khazanchi and a poet in his own rights introduced him to Thakur Ranbir Singh, (played by K. N. Singh) the local big shoot. The latter hoisted a party in his honour. It was there that he met Ameeta 'Naaz' (played by Meena Mumtaz) who was laos a poetess. Being a responsible executive he forgot all about the party and Ameeta too who by her tempting looks held him spellbound that colourful evening. Once the work was over, he made a bye-line to his house where his darling son (played by Raja) and charming wife Sudha (played by Kamini Kaushal) greeted him with a broad samile. More than anything in the world, he loved his wife and son.
As the luck would have it, Sudha had to leave the town to see her ailing mother at Agra and she also took child with her. Balraj now felt lonely, especially in the evening, when the work was over. One evening, Tripathi (played by Balam) the local police officer and Balraj's erstwhile class-fellow, took him to a 'Mushaira' where he again met Ameeta and at the end of the gathering, she gave him a lift to his residencee and became too familiar to be avoided. Balraj soon found himself entangled in her charm. Although, of dubious reputation, Balraj even accepted to visit her at her residence. Balraj didn't suspect it for a moment that it was about a booby-trap! Ameeta drugged him and removed the keys of the safe from his person.
But that was not all. Goes an old adage 'Misfortunes do not befall man singly but in cohorts'. When Balraj was himself again at the dead of night, he found Ameeta lying in a pool of blood. She has been dead of night, he found Ameeta lying in a pool of blood. She had been murdered by an unknown assassin. He rushed home in panic. Next morning more bad news awaited him. The bank had been looted and chowkidar murdered! On top of it the clients had lost faith in the bank and they had assembled in the premises to demand payments of their deposits. Amidst such horrifying incidents, his wife returned only to recieve the stunning news of Balraj's involvemnet in murder and Bank robbery. Trapped in circumstantial evidence, Balraj had to abscond leaving his sick child and wife in utter misery.
Was Balraj really guilty? If not then who engineered the murders and bank robbery? For all these clues dear patrons, yu will have to see 'Bank Manager' from beginning to end.
