In the pre-partition days in the cosmopolitan town of Maler Kotla, three sets of twins are born: Hukum Singh&Hukum Din (Kulbhushan Kharbanda
), Karam Singh&Karam Din (Rakesh Bedi
) and Bhuja Singh Bhuchal&Bhuja Singh Tufian (Rana Jung Bahadur
Daulat Singh, a rich landlord, is living a satisfied life with his wife Noorbano and two sons - Hukum Singh and Hukum Din. Living alongside him is his good friend llam Din and his wife and two sons - Karam Singh and Karam Din. The partition forces llam Din to move to Lahore. In the hustle and bustle, llam Din accidentally takes one of Daulat Singh's sons, leaving his own behind.
Cut to 2005: Hukum Singh and Karam Singh are living a pleasant life in Maler Kotla. That changes with the arrival of the troublesome duo of Hukum Din and Karam Din from Lahore. Coming in disguise as part of a Pakistan Cultural delegation, they hatch a plan to discover wealth. However, thanks to the suspicious eyes of Inspector Bujja Singh Bhuchaal, things don't go as planned for them.
The story however is not that simple. Caught in this comedy of errors is the love story of Rosy, Hukum Singh's only daughter who has fallen for Jassi, a budding pop singer. This news meets with strong disapproval from both Hukum and Karam Singh, who cannot stand the sight of singers! Hukum Singh desires his daughter to be married to Ranjit, son of his 'asylum confined' friend Bujja Singh Toofan.
Will the long lost brothers finally meet each other? Will Rosy marry the love of her Hfe? Will Hukum Din and Karam Din be able to escape from Inspector Bhuchaal's hold? What does the future hold for the asylum runaway Bhuja Singh Toofan?
